There is a scenario where the\nFFS application issues an AIO cancel call, while the UDC is handling a\nsoft disconnect.  For a DWC3 based implementation, the callstack looks\nlike the following:\r\n\r\n    DWC3 Gadget                               FFS Application\ndwc3_gadget_soft_disconnect()              ...\n  --\u0026gt; dwc3_stop_active_transfers()\n    --\u0026gt; dwc3_gadget_giveback(-ESHUTDOWN)\n      --\u0026gt; ffs_epfile_async_io_complete()   ffs_aio_cancel()\n        --\u0026gt; usb_ep_free_request()            --\u0026gt; usb_ep_dequeue()\r\n\r\nThere is currently no locking implemented between the AIO completion\nhandler and AIO cancel, so the issue occurs if the completion routine is\nrunning in parallel to an AIO cancel call coming from the FFS application.\nAs the completion call frees the USB request (io_data-\u0026gt;req) the FFS\napplication is also referencing it for the usb_ep_dequeue() call.  This can\nlead to accessing a stale/hanging pointer.\r\n\r\ncommit b566d38857fc (\u0026quot;usb: gadget: f_fs: use io_data-\u0026gt;status consistently\u0026quot;)\nrelocated the usb_ep_free_request() into ffs_epfile_async_io_complete().\nHowever, in order to properly implement locking to mitigate this issue, the\nspinlock can\u0026apos;t be added to ffs_epfile_async_io_complete(), as\nusb_ep_dequeue() (if successfully dequeuing a USB request) will call the\nfunction driver\u0026apos;s completion handler in the same context.  Hence, leading\ninto a deadlock.\r\n\r\nFix this issue by moving the usb_ep_free_request() back to\nffs_user_copy_worker(), and ensuring that it explicitly sets io_data-\u0026gt;req\nto NULL after freeing it within the ffs-\u0026gt;eps_lock.  This resolves the race\ncondition above, as the ffs_aio_cancel() routine will not continue\nattempting to dequeue a request that has already been freed, or the\nffs_user_copy_work() not freeing the USB request until the AIO cancel is\ndone referencing it.\r\n\r\nThis fix depends on\n  commit b566d38857fc (\u0026quot;usb: gadget: f_fs: use io_data-\u0026gt;status\n  consistently\u0026quot;)(CVE-2024-36894)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nscsi: bfa: Ensure the copied buf is NUL terminated\r\n\r\nCurrently, we allocate a nbytes-sized kernel buffer and copy nbytes from\nuserspace to that buffer. Later, we use sscanf on this buffer but we don\u0026apos;t\nensure that the string is terminated inside the buffer, this can lead to\nOOB read when using sscanf. Fix this issue by using memdup_user_nul instead\nof memdup_user.(CVE-2024-38560)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nenic: Validate length of nl attributes in enic_set_vf_port\r\n\r\nenic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILE\nis of length PORT_PROFILE_MAX and that the nl attributes\nIFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX.\nThese attributes are validated (in the function do_setlink in rtnetlink.c)\nusing the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILE\nas NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY and\nIFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validation\nusing the policy is for the max size of the attributes and not on exact\nsize so the length of these attributes might be less than the sizes that\nenic_set_vf_port expects. This might cause an out of bands\nread access in the memcpys of the data of these\nattributes in enic_set_vf_port.(CVE-2024-38659)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbcache: fix variable length array abuse in btree_iter\r\n\r\nbtree_iter is used in two ways: either allocated on the stack with a\nfixed size MAX_BSETS, or from a mempool with a dynamic size based on the\nspecific cache set. Previously, the struct had a fixed-length array of\nsize MAX_BSETS which was indexed out-of-bounds for the dynamically-sized\niterators, which causes UBSAN to complain.\r\n\r\nThis patch uses the same approach as in bcachefs\u0026apos;s sort_iter and splits\nthe iterator into a btree_iter with a flexible array member and a\nbtree_iter_stack which embeds a btree_iter as well as a fixed-length\ndata array.(CVE-2024-39482)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nksmbd: discard write access to the directory open\r\n\r\nmay_open() does not allow a directory to be opened with the write access.\nHowever, some writing flags set by client result in adding write access\non server, making ksmbd incompatible with FUSE file system.

This could lead to\npossible serious problems, such as LRU list crashes due to holding the\nwrong LRU lock, and incorrect LRU statistics.\n\nTo fix this issue, we can fallback to use the mem_cgroup_replace_folio()\nto replace the old shmem folio.\n\n[ 5241.100311] page: refcount:0 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x5d9960\n[ 5241.100317] head: order:4 mapcount:0 entire_mapcount:0 nr_pages_mapped:0 pincount:0\n[ 5241.100319] flags: 0x17fffe0000040068(uptodate|lru|head|swapbacked|node=0|zone=2|lastcpupid=0x3ffff)\n[ 5241.100323] raw: 17fffe0000040068 fffffdffd6687948 fffffdffd69ae008 0000000000000000\n[ 5241.100325] raw: 0000000000000000 0000000000000000 00000000ffffffff 0000000000000000\n[ 5241.100326] head: 17fffe0000040068 fffffdffd6687948 fffffdffd69ae008 0000000000000000\n[ 5241.100327] head: 0000000000000000 0000000000000000 00000000ffffffff 0000000000000000\n[ 5241.100328] head: 17fffe0000000204 fffffdffd6665801 ffffffffffffffff 0000000000000000\n[ 5241.100329] head: 0000000a00000010 0000000000000000 00000000ffffffff 0000000000000000\n[ 5241.100330] page dumped because: VM_WARN_ON_ONCE_FOLIO(!memcg \u0026amp;\u0026amp;

Either the link has failed and the system is in need\nof maintenance, or the link continues to work and user has been informed.\nThe message from the warning can be looked up in the sources.\n\nThis makes an actual link issue less verbose.\n\nFirst of all, this controller has a limitation in that the controller\ndriver has to assist the hardware with transition to L1 link state by\nwriting L1IATN to PMCTRL register, the L1 and L0 link state switching\nis not fully automatic on this controller.\n\nIn case of an ASMedia ASM1062 PCIe SATA controller which does not support\nASPM, on entry to suspend or during platform pm_test, the SATA controller\nenters D3hot state and the link enters L1 state. If the SATA controller\nwakes up before rcar_pcie_wakeup() was called and returns to D0, the link\nreturns to L0 before the controller driver even started its transition to\nL1 link state. At this point, the SATA controller did send an PM_ENTER_L1\nDLLP to the PCIe controller and the PCIe controller received it, and the\nPCIe controller did set PMSR PMEL1RX bit.\n\nOnce rcar_pcie_wakeup() is called, if the link is already back in L0 state\nand PMEL1RX bit is set, the controller driver has no way to determine if\nit should perform the link transition to L1 state, or treat the link as if\nit is in L0 state. Currently the driver attempts to perform the transition\nto L1 link state unconditionally, which in this specific case fails with a\nPMSR L1FAEG poll timeout, however the link still works as it is already\nback in L0 state.\n\nReduce this warning verbosity. In case the link is really broken, the\nrcar_pcie_config_access() would fail, otherwise it will succeed and any\nsystem with this controller and ASM1062 can suspend without generating\na backtrace.(CVE-2024-43876)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nmedia: pci: ivtv: Add check for DMA map result\n\nIn case DMA fails, \u0026apos;dma-\u0026gt;SG_length\u0026apos; is 0.

Adjust warnings accordingly.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.(CVE-2024-43877)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nmlxsw: spectrum_acl_erp: Fix object nesting warning\n\nACLs in Spectrum-2 and newer ASICs can reside in the algorithmic TCAM\n(A-TCAM) or in the ordinary circuit TCAM (C-TCAM). The former can\ncontain more ACLs (i.e., tc filters), but the number of masks in each\nregion (i.e., tc chain) is limited.\n\nIn order to mitigate the effects of the above limitation, the device\nallows filters to share a single mask if their masks only differ in up\nto 8 consecutive bits. For example, dst_ip/25 can be represented using\ndst_ip/24 with a delta of 1 bit. The C-TCAM does not have a limit on the\nnumber of masks being used (and therefore does not support mask\naggregation), but can contain a limited number of filters.\n\nThe driver uses the \u0026quot;objagg\u0026quot; library to perform the mask aggregation by\npassing it objects that consist of the filter\u0026apos;s mask and whether the\nfilter is to be inserted into the A-TCAM or the C-TCAM since filters in\ndifferent TCAMs cannot share a mask.\n\nThe set of created objects is dependent on the insertion order of the\nfilters and is not necessarily optimal. Therefore, the driver will\nperiodically ask the library to compute a more optimal set (\u0026quot;hints\u0026quot;) by\nlooking at all the existing objects.\n\nWhen the library asks the driver whether two objects can be aggregated\nthe driver only compares the provided masks and ignores the A-TCAM /\nC-TCAM indication. This is the right thing to do since the goal is to\nmove as many filters as possible to the A-TCAM. The driver also forbids\ntwo identical masks from being aggregated since this can only happen if\none was intentionally put in the C-TCAM to avoid a conflict in the\nA-TCAM.\n\nThe above can result in the following set of hints:\n\nH1: {mask X, A-TCAM} -\u0026gt; H2: {mask Y, A-TCAM} // X is Y + delta\nH3: {mask Y, C-TCAM} -\u0026gt; H4: {mask Z, A-TCAM} // Y is Z + delta\n\nAfter getting the hints from the library the driver will start migrating\nfilters from one region to another while consulting the computed hints\nand instructing the device to perform a lookup in both regions during\nthe transition.\n\nAssuming a filter with mask X is being migrated into the A-TCAM in the\nnew region, the hints lookup will return H1. Since H2 is the parent of\nH1, the library will try to find the object associated with it and\ncreate it if necessary in which case another hints lookup (recursive)\nwill be performed. This hints lookup for {mask Y, A-TCAM} will either\nreturn H2 or H3 since the driver passes the library an object comparison\nfunction that ignores the A-TCAM / C-TCAM indication.\n\nThis can eventually lead to nested objects which are not supported by\nthe library [1].\n\nFix by removing the object comparison function from both the driver and\nthe library as the driver was the only user. That way the lookup will\nonly return exact matches.\n\nI do not have a reliable reproducer that can reproduce the issue in a\ntimely manner, but before the fix the issue would reproduce in several\nminutes and with the fix it does not reproduce in over an hour.\n\nNote that the current usefulness of the hints is limited because they\ninclude the C-TCAM indication and represent aggregation that cannot\nactually happen. This will be addressed in net-next.\n\n[1]\nWARNING: CPU: 0 PID: 153 at lib/objagg.c:170 objagg_obj_parent_assign+0xb5/0xd0\nModules linked in:\nCPU: 0 PID: 153 Comm: kworker/0:18 Not tainted 6.9.0-rc6-custom-g70fbc2c1c38b #42\nHardware name: Mellanox Technologies Ltd.

However, since commit e9c3cda4d86e (\u0026quot;mm,\nvmalloc: fix high order __GFP_NOFAIL allocations\u0026quot;), if gfp_flags includes\n__GFP_NOFAIL with high order in vm_area_alloc_pages() and page allocation\nfailed for high order, the pages** may contain two different page shifts\n(high order and order-0).  This could lead __vmap_pages_range_noflush() to\nperform incorrect mappings, potentially resulting in memory corruption.\n\nUsers might encounter this as follows (vmap_allow_huge = true, 2M is for\nPMD_SIZE):\n\nkvmalloc(2M, __GFP_NOFAIL|GFP_X)\n    __vmalloc_node_range_noprof(vm_flags=VM_ALLOW_HUGE_VMAP)\n        vm_area_alloc_pages(order=9) ---\u0026gt; order-9 allocation failed and fallback to order-0\n            vmap_pages_range()\n                vmap_pages_range_noflush()\n                    __vmap_pages_range_noflush(page_shift = 21) ----\u0026gt; wrong mapping happens\n\nWe can remove the fallback code because if a high-order allocation fails,\n__vmalloc_node_range_noprof() will retry with order-0.  Therefore, it is\nunnecessary to fallback to order-0 here.  Therefore, fix this by removing\nthe fallback code.(CVE-2024-45022)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nwifi: brcmfmac: cfg80211: Handle SSID based pmksa deletion\n\nwpa_supplicant 2.11 sends since 1efdba5fdc2c (\u0026quot;Handle PMKSA flush in the\ndriver for SAE/OWE offload cases\u0026quot;) SSID based PMKSA del commands.\nbrcmfmac is not prepared and tries to dereference the NULL bssid and\npmkid pointers in cfg80211_pmksa.

However, in hv_machine_shutdown(), the cpuhp_remove_state() call\nis conditioned upon \u0026quot;hyperv_init_cpuhp \u0026gt; 0\u0026quot;. This will never be true and\nso hv_cpu_die() won\u0026apos;t be called on all CPUs. This means the VP assist page\nwon\u0026apos;t be reset. When the kexec kernel tries to setup the VP assist page\nagain, the hypervisor corrupts the memory region of the old VP assist page\ncausing a panic in case the kexec kernel is using that memory elsewhere.\nThis was originally fixed in commit dfe94d4086e4 (\u0026quot;x86/hyperv: Fix kexec\npanic/hang issues\u0026quot;).\n\nGet rid of hyperv_init_cpuhp entirely since we are no longer using a\ndynamic cpuhp state and use CPUHP_AP_HYPERV_ONLINE directly with\ncpuhp_remove_state().(CVE-2024-46864)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nfou: fix initialization of grc\n\nThe grc must be initialize first.

This results in undefined behavior, as UBSan\nreports:\n\nnet.c:827:2: runtime error: null pointer passed as argument 1, which is declared to never be null\n\nAlthough the C standard does not explicitly state whether calling qsort\nwith a NULL pointer when the size is 0 constitutes undefined behavior,\nSection 7.1.4 of the C standard (Use of library functions) mentions:\n\n\u0026quot;Each of the following statements applies unless explicitly stated\notherwise in the detailed descriptions that follow: If an argument to a\nfunction has an invalid value (such as a value outside the domain of\nthe function, or a pointer outside the address space of the program, or\na null pointer, or a pointer to non-modifiable storage when the\ncorresponding parameter is not const-qualified) or a type (after\npromotion) not expected by a function with variable number of\narguments, the behavior is undefined.\u0026quot;\n\nTo avoid this, add an early return when nf_link_info is NULL to prevent\ncalling qsort with a NULL pointer.(CVE-2024-49987)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: add refcnt to ksmbd_conn struct\n\nWhen sending an oplock break request, opinfo-\u0026gt;conn is used,\nBut freed -\u0026gt;conn can be used on multichannel.\nThis patch add a reference count to the ksmbd_conn struct\nso that it can be freed when it is no longer used.(CVE-2024-49988)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: improve shutdown sequence\n\nAlexander Sverdlin presents 2 problems during shutdown with the\nlan9303 driver. One is specific to lan9303 and the other just happens\nto reproduce there.\n\nThe first problem is that lan9303 is unique among DSA drivers in that it\ncalls dev_get_drvdata() at \u0026quot;arbitrary runtime\u0026quot; (not probe, not shutdown,\nnot remove):\n\nphy_state_machine()\n-\u0026gt; ...\n   -\u0026gt; dsa_user_phy_read()\n      -\u0026gt; ds-\u0026gt;ops-\u0026gt;phy_read()\n         -\u0026gt; lan9303_phy_read()\n            -\u0026gt; chip-\u0026gt;ops-\u0026gt;phy_read()\n               -\u0026gt; lan9303_mdio_phy_read()\n                  -\u0026gt; dev_get_drvdata()\n\nBut we never stop the phy_state_machine(), so it may continue to run\nafter dsa_switch_shutdown(). Our common pattern in all DSA drivers is\nto set drvdata to NULL to suppress the remove() method that may come\nafterwards. But in this case it will result in an NPD.\n\nThe second problem is that the way in which we set\ndp-\u0026gt;conduit-\u0026gt;dsa_ptr = NULL; is concurrent with receive packet\nprocessing. dsa_switch_rcv() checks once whether dev-\u0026gt;dsa_ptr is NULL,\nbut afterwards, rather than continuing to use that non-NULL value,\ndev-\u0026gt;dsa_ptr is dereferenced again and again without NULL checks:\ndsa_conduit_find_user() and many other places. In between dereferences,\nthere is no locking to ensure that what was valid once continues to be\nvalid.\n\nBoth problems have the common aspect that closing the conduit interface\nsolves them.\n\nIn the first case, dev_close(conduit) triggers the NETDEV_GOING_DOWN\nevent in dsa_user_netdevice_event() which closes user ports as well.\ndsa_port_disable_rt() calls phylink_stop(), which synchronously stops\nthe phylink state machine, and ds-\u0026gt;ops-\u0026gt;phy_read() will thus no longer\ncall into the driver after this point.\n\nIn the second case, dev_close(conduit) should do this, as per\nDocumentation/networking/driver.rst:\n\n| Quiescence\n| ----------\n|\n| After the ndo_stop routine has been called, the hardware must\n| not receive or transmit any data.

If the address did not\nchange, then the above would result in increasing the reference count of\nthe address and then decreasing it.\n\n[1]\n # ip link add name bla up type ip6gre local 2001:db8:1::1 remote 2001:db8:2::1 tos inherit ttl inherit\n # ip link set dev bla type ip6gre remote 2001:db8:3::1\n # ip link del dev bla\n # devlink dev reload pci/0000:01:00.0\n\n[2]\nWARNING: CPU: 0 PID: 1682 at drivers/net/ethernet/mellanox/mlxsw/spectrum.c:3002 mlxsw_sp_ipv6_addr_put+0x140/0x1d0\nModules linked in:\nCPU: 0 UID: 0 PID: 1682 Comm: ip Not tainted 6.12.0-rc3-custom-g86b5b55bc835 #151\nHardware name: Nvidia SN5600/VMOD0013, BIOS 5.13 05/31/2023\nRIP: 0010:mlxsw_sp_ipv6_addr_put+0x140/0x1d0\n[...]\nCall Trace:\n \u0026lt;TASK\u0026gt;\n mlxsw_sp_router_netdevice_event+0x55f/0x1240\n notifier_call_chain+0x5a/0xd0\n call_netdevice_notifiers_info+0x39/0x90\n unregister_netdevice_many_notify+0x63e/0x9d0\n rtnl_dellink+0x16b/0x3a0\n rtnetlink_rcv_msg+0x142/0x3f0\n netlink_rcv_skb+0x50/0x100\n netlink_unicast+0x242/0x390\n netlink_sendmsg+0x1de/0x420\n ____sys_sendmsg+0x2bd/0x320\n ___sys_sendmsg+0x9a/0xe0\n __sys_sendmsg+0x7a/0xd0\n do_syscall_64+0x9e/0x1a0\n entry_SYSCALL_64_after_hwframe+0x77/0x7f\n\n[3]\nunreferenced object 0xffff898081f597a0 (size 32):\n  comm \u0026quot;ip\u0026quot;, pid 1626, jiffies 4294719324\n  hex dump (first 32 bytes):\n    20 01 0d b8 00 02 00 00 00 00 00 00 00 00 00 01   ...............\n    21 49 61 83 80 89 ff ff 00 00 00 00 01 00 00 00  !Ia.............\n  backtrace (crc fd9be911):\n    [\u0026lt;00000000df89c55d\u0026gt;] __kmalloc_cache_noprof+0x1da/0x260\n    [\u0026lt;00000000ff2a1ddb\u0026gt;] mlxsw_sp_ipv6_addr_kvdl_index_get+0x281/0x340\n    [\u0026lt;000000009ddd445d\u0026gt;] mlxsw_sp_router_netdevice_event+0x47b/0x1240\n    [\u0026lt;00000000743e7757\u0026gt;] notifier_call_chain+0x5a/0xd0\n    [\u0026lt;000000007c7b9e13\u0026gt;] call_netdevice_notifiers_info+0x39/0x90\n    [\u0026lt;000000002509645d\u0026gt;] register_netdevice+0x5f7/0x7a0\n    [\u0026lt;00000000c2e7d2a9\u0026gt;] ip6gre_newlink_common.isra.0+0x65/0x130\n    [\u0026lt;0000000087cd6d8d\u0026gt;] ip6gre_newlink+0x72/0x120\n    [\u0026lt;000000004df7c7cc\u0026gt;] rtnl_newlink+0x471/0xa20\n    [\u0026lt;0000000057ed632a\u0026gt;] rtnetlink_rcv_msg+0x142/0x3f0\n    [\u0026lt;0000000032e0d5b5\u0026gt;] netlink_rcv_skb+0x50/0x100\n    [\u0026lt;00000000908bca63\u0026gt;] netlink_unicast+0x242/0x390\n    [\u0026lt;00000000cdbe1c87\u0026gt;] netlink_sendmsg+0x1de/0x420\n    [\u0026lt;0000000011db153e\u0026gt;] ____sys_sendmsg+0x2bd/0x320\n    [\u0026lt;000000003b6d53eb\u0026gt;] ___sys_sendmsg+0x9a/0xe0\n    [\u0026lt;00000000cae27c62\u0026gt;] __sys_sendmsg+0x7a/0xd0(CVE-2024-50252)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_reject_ipv6: fix potential crash in nf_send_reset6()\n\nI got a syzbot report without a repro [1] crashing in nf_send_reset6()\n\nI think the issue is that dev-\u0026gt;hard_header_len is zero, and we attempt\nlater to push an Ethernet header.\n\nUse LL_MAX_HEADER, as other functions in net/ipv6/netfilter/nf_reject_ipv6.c.\n\n[1]\n\nskbuff: skb_under_panic: text:ffffffff89b1d008 len:74 put:14 head:ffff88803123aa00 data:ffff88803123a9f2 tail:0x3c end:0x140 dev:syz_tun\n kernel BUG at net/core/skbuff.c:206 !\nOops: invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI\nCPU: 0 UID: 0 PID: 7373 Comm: syz.1.568 Not tainted 6.12.0-rc2-syzkaller-00631-g6d858708d465 #0\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 09/13/2024\n RIP: 0010:skb_panic net/core/skbuff.c:206 [inline]\n RIP: 0010:skb_under_panic+0x14b/0x150 net/core/skbuff.c:216\nCode: 0d 8d 48 c7 c6 60 a6 29 8e 48 8b 54 24 08 8b 0c 24 44 8b 44 24 04 4d 89 e9 50 41 54 41 57 41 56 e8 ba 30 38 02 48 83 c4 20 90 \u0026lt;0f\u0026gt;

In this scenario, fs_core may set the\nhardware deletion function to NULL prematurely, causing a panic during\nsubsequent rule deletions.\n\nTo prevent this, ensure the active flag of the FTE is checked under a lock,\nwhich will prevent the fs_core layer from attaching a new steering rule to\nan FTE that is in the process of deletion.\n\n[  438.967589] MOSHE: 2496 mlx5_del_flow_rules del_hw_func\n[  438.968205] ------------[ cut here ]------------\n[  438.968654] refcount_t: decrement hit 0;

There are\nmyriad bugs in the implementation, some of which are fatal to the guest,\nand others which put the stability and health of the host at risk.\n\nFor guest fatalities, the most glaring issue is that KVM fails to ensure\ntracing is disabled, and *stays* disabled prior to VM-Enter, which is\nnecessary as hardware disallows loading (the guest\u0026apos;s) RTIT_CTL if tracing\nis enabled (enforced via a VMX consistency check).  Per the SDM:\n\n  If the logical processor is operating with Intel PT enabled (if\n  IA32_RTIT_CTL.TraceEn = 1) at the time of VM entry, the \u0026quot;load\n  IA32_RTIT_CTL\u0026quot; VM-entry control must be 0.\n\nOn the host side, KVM doesn\u0026apos;t validate the guest CPUID configuration\nprovided by userspace, and even worse, uses the guest configuration to\ndecide what MSRs to save/load at VM-Enter and VM-Exit.  E.g. configuring\nguest CPUID to enumerate more address ranges than are supported in hardware\nwill result in KVM trying to passthrough, save, and load non-existent MSRs,\nwhich generates a variety of WARNs, ToPA ERRORs in the host, a potential\ndeadlock, etc.(CVE-2024-53135)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5e: kTLS, Fix incorrect page refcounting\n\nThe kTLS tx handling code is using a mix of get_page() and\npage_ref_inc() APIs to increment the page reference. But on the release\npath (mlx5e_ktls_tx_handle_resync_dump_comp()), only put_page() is used.\n\nThis is an issue when using pages from large folios: the get_page()\nreferences are stored on the folio page while the page_ref_inc()\nreferences are stored directly in the given page. On release the folio\npage will be dereferenced too many times.\n\nThis was found while doing kTLS testing with sendfile() + ZC when the\nserved file was read from NFS on a kernel with NFS large folios support\n(commit 49b29a573da8 (\u0026quot;nfs: add support for large folios\u0026quot;)).(CVE-2024-53138)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nsctp: fix possible UAF in sctp_v6_available()\n\nA lockdep report [1] with CONFIG_PROVE_RCU_LIST=y hints\nthat sctp_v6_available() is calling dev_get_by_index_rcu()\nand ipv6_chk_addr() without holding rcu.\n\n[1]\n =============================\n WARNING: suspicious RCU usage\n 6.12.0-rc5-virtme #1216 Tainted: G        W\n -----------------------------\n net/core/dev.c:876 RCU-list traversed in non-reader section!!\n\nother info that might help us debug this:\n\nrcu_scheduler_active = 2, debug_locks = 1\n 1 lock held by sctp_hello/31495:\n #0: ffff9f1ebbdb7418 (sk_lock-AF_INET6){+.+.}-{0:0}, at: sctp_bind (./arch/x86/include/asm/jump_label.h:27 net/sctp/socket.c:315) sctp\n\nstack backtrace:\n CPU: 7 UID: 0 PID: 31495 Comm: sctp_hello Tainted: G        W          6.12.0-rc5-virtme #1216\n Tainted: [W]=WARN\n Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-debian-1.16.3-2 04/01/2014\n Call Trace:\n  \u0026lt;TASK\u0026gt;\n dump_stack_lvl (lib/dump_stack.c:123)\n lockdep_rcu_suspicious (kernel/locking/lockdep.c:6822)\n dev_get_by_index_rcu (net/core/dev.c:876 (discriminator 7))\n sctp_v6_available (net/sctp/ipv6.c:701) sctp\n sctp_do_bind (net/sctp/socket.c:400 (discriminator 1)) sctp\n sctp_bind (net/sctp/socket.c:320) sctp\n inet6_bind_sk (net/ipv6/af_inet6.c:465)\n ? security_socket_bind (security/security.c:4581 (discriminator 1))\n __sys_bind (net/socket.c:1848 net/socket.c:1869)\n ? do_user_addr_fault (./include/linux/rcupdate.h:347 ./include/linux/rcupdate.h:880 ./include/linux/mm.h:729 arch/x86/mm/fault.c:1340)\n ? do_user_addr_fault (./arch/x86/include/asm/preempt.h:84 (discriminator 13) ./include/linux/rcupdate.h:98 (discriminator 13) ./include/linux/rcupdate.h:882 (discriminator 13) ./include/linux/mm.h:729 (discriminator 13) arch/x86/mm/fault.c:1340 (discriminator 13))\n __x64_sys_bind (net/socket.c:1877 (discriminator 1) net/socket.c:1875 (discriminator 1) net/socket.c:1875 (discriminator 1))\n do_syscall_64 (arch/x86/entry/common.c:52 (discriminator 1) arch/x86/entry/common.c:83 (discriminator 1))\n entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130)\n RIP: 0033:0x7f59b934a1e7\n Code: 44 00 00 48 8b 15 39 8c 0c 00 f7 d8 64 89 02 b8 ff ff ff ff eb bd 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 00 b8 31 00 00 00 0f 05 \u0026lt;48\u0026gt; 3d 01 f0 ff ff 73 01 c3 48 8b 0d 09 8c 0c 00 f7 d8 64 89 01 48\nAll code\n========\n   0:\t44 00 00             \tadd    %r8b,(%rax)\n   3:\t48 8b 15 39 8c 0c 00 \tmov    0xc8c39(%rip),%rdx        # 0xc8c43\n   a:\tf7 d8                \tneg    %eax\n   c:\t64 89 02             \tmov    %eax,%fs:(%rdx)\n   f:\tb8 ff ff ff ff       \tmov    $0xffffffff,%eax\n  14:\teb bd                \tjmp    0xffffffffffffffd3\n  16:\t66 2e 0f 1f 84 00 00 \tcs nopw 0x0(%rax,%rax,1)\n  1d:\t00 00 00\n  20:\t0f 1f 00             \tnopl   (%rax)\n  23:\tb8 31 00 00 00       \tmov    $0x31,%eax\n  28:\t0f 05                \tsyscall\n  2a:*\t48 3d 01 f0 ff ff    \tcmp    $0xfffffffffffff001,%rax\t\t\u0026lt;-- trapping instruction\n  30:\t73 01                \tjae    0x33\n  32:\tc3                   \tret\n  33:\t48 8b 0d 09 8c 0c 00 \tmov    0xc8c09(%rip),%rcx        # 0xc8c43\n  3a:\tf7 d8                \tneg    %eax\n  3c:\t64 89 01             \tmov    %eax,%fs:(%rcx)\n  3f:\t48                   \trex.W\n\nCode starting with the faulting instruction\n===========================================\n   0:\t48 3d 01 f0 ff ff    \tcmp    $0xfffffffffffff001,%rax\n   6:\t73 01                \tjae    0x9\n   8:\tc3                   \tret\n   9:\t48 8b 0d 09 8c 0c 00 \tmov    0xc8c09(%rip),%rcx        # 0xc8c19\n  10:\tf7 d8                \tneg    %eax\n  12:\t64 89 01             \tmov    %eax,%fs:(%rcx)\n  15:\t48                   \trex.W\n RSP: 002b:00007ffe2d0ad398 EFLAGS: 00000202 ORIG_RAX: 0000000000000031\n RAX: ffffffffffffffda RBX: 00007ffe2d0ad3d0 RCX: 00007f59b934a1e7\n RDX: 000000000000001c RSI: 00007ffe2d0ad3d0 RDI: 0000000000000005\n RBP: 0000000000000005 R08: 1999999999999999 R09: 0000000000000000\n R10: 00007f59b9253298 R11: 000000000000\n---truncated---(CVE-2024-53139)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nnetlink: terminate outstanding dump on socket close\n\nNetlink supports iterative dumping of data. It provides the families\nthe following ops:\n - start - (optional) kicks off the dumping process\n - dump  - actual dump helper, keeps getting called until it returns 0\n - done  - (optional) pairs with .start, can be used for cleanup\nThe whole process is asynchronous and the repeated calls to .dump\ndon\u0026apos;t actually happen in a tight loop, but rather are triggered\nin response to recvmsg() on the socket.\n\nThis gives the user full control over the dump, but also means that\nthe user can close the socket without getting to the end of the dump.\nTo make sure .start is always paired with .done we check if there\nis an ongoing dump before freeing the socket, and if so call .done.\n\nThe complication is that sockets can get freed from BH and .done\nis allowed to sleep. So we use a workqueue to defer the call, when\nneeded.\n\nUnfortunately this does not work correctly. What we defer is not\nthe cleanup but rather releasing a reference on the socket.\nWe have no guarantee that we own the last reference, if someone\nelse holds the socket they may release it in BH and we\u0026apos;re back\nto square one.\n\nThe whole dance, however, appears to be unnecessary.

Use the kthread_stop\nas the main signal to exit dpc_thread.\n\n[596663.812935] kernel BUG at mm/slub.c:294!\n[596663.812950] invalid opcode: 0000 [#1] SMP PTI\n[596663.812957] CPU: 13 PID: 1475935 Comm: rmmod Kdump: loaded Tainted: G          IOE    --------- -  - 4.18.0-240.el8.x86_64 #1\n[596663.812960] Hardware name: HP ProLiant DL380p Gen8, BIOS P70 08/20/2012\n[596663.812974] RIP: 0010:__slab_free+0x17d/0x360\n\n...\n[596663.813008] Call Trace:\n[596663.813022]  ? __dentry_kill+0x121/0x170\n[596663.813030]  ? _cond_resched+0x15/0x30\n[596663.813034]  ? _cond_resched+0x15/0x30\n[596663.813039]  ? wait_for_completion+0x35/0x190\n[596663.813048]  ? try_to_wake_up+0x63/0x540\n[596663.813055]  free_task+0x5a/0x60\n[596663.813061]  kthread_stop+0xf3/0x100\n[596663.813103]  qla2x00_remove_one+0x284/0x440 [qla2xxx](CVE-2024-56623)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nnet/smc: fix LGR and link use-after-free issue\n\nWe encountered a LGR/link use-after-free issue, which manifested as\nthe LGR/link refcnt reaching 0 early and entering the clear process,\nmaking resource access unsafe.\n\n refcount_t: addition on 0; use-after-free.\n WARNING: CPU: 14 PID: 107447 at lib/refcount.c:25 refcount_warn_saturate+0x9c/0x140\n Workqueue: events smc_lgr_terminate_work [smc]\n Call trace:\n  refcount_warn_saturate+0x9c/0x140\n  __smc_lgr_terminate.part.45+0x2a8/0x370 [smc]\n  smc_lgr_terminate_work+0x28/0x30 [smc]\n  process_one_work+0x1b8/0x420\n  worker_thread+0x158/0x510\n  kthread+0x114/0x118\n\nor\n\n refcount_t: underflow; use-after-free.\n WARNING: CPU: 6 PID: 93140 at lib/refcount.c:28 refcount_warn_saturate+0xf0/0x140\n Workqueue: smc_hs_wq smc_listen_work [smc]\n Call trace:\n  refcount_warn_saturate+0xf0/0x140\n  smcr_link_put+0x1cc/0x1d8 [smc]\n  smc_conn_free+0x110/0x1b0 [smc]\n  smc_conn_abort+0x50/0x60 [smc]\n  smc_listen_find_device+0x75c/0x790 [smc]\n  smc_listen_work+0x368/0x8a0 [smc]\n  process_one_work+0x1b8/0x420\n  worker_thread+0x158/0x510\n  kthread+0x114/0x118\n\nIt is caused by repeated release of LGR/link refcnt.

The gadget is initialized using musb_gadget_enable().\n2. Meanwhile, a packet arrives, and the RXPKTRDY flag is set, raising an\n   interrupt.\n3. If IRQs are enabled, the interrupt is handled, but musb_g_rx() finds an\n   empty queue (next_request() returns NULL). The interrupt flag has\n   already been cleared by the glue layer handler, but the RXPKTRDY flag\n   remains set.\n4. The first request is enqueued using usb_ep_queue(), leading to the call\n   of req-\u0026gt;complete(), as shown in the call trace above.\n5. If the callback enables IRQs and another packet is waiting, step (3)\n   repeats. The request queue is empty because usb_g_giveback() removes the\n   request before invoking the callback.\n6. The endpoint remains locked up, as the interrupt triggered by hardware\n   setting the RXPKTRDY flag has been handled, but the flag itself remains\n   set.\n\nFor this scenario to occur, it is only necessary for IRQs to be enabled at\nsome point during the complete callback. This happens with the USB Ethernet\ngadget, whose rx_complete() callback calls netif_rx(). If called in the\ntask context, netif_rx() disables the bottom halves (BHs). When the BHs are\nre-enabled, IRQs are also enabled to allow soft IRQs to be processed. The\ngadget itself is initialized at module load (or at boot if built-in), but\nthe first request is enqueued when the network interface is brought up,\ntriggering rx_complete() in the task context via ioctl(). If a packet\narrives while the interface is down, it can prevent the interface from\nreceiving any further packets from the USB host.\n\nThe situation is quite complicated with many parties involved. This\nparticular issue can be resolved in several possible ways:\n\n1. Ensure that callbacks never enable IRQs. This would be difficult to\n   enforce, as discovering how netif_rx() interacts with interrupts was\n   already quite challenging and u_ether is not the only function driver.\n   Similar \u0026quot;bugs\u0026quot; could be hidden in other drivers as well.\n2. Disable MUSB interrupts in musb_g_giveback() before calling the callback\n   and re-enable them afterwars (by calling musb_{dis,en}able_interrupts(),\n   for example). This would ensure that MUSB interrupts are not handled\n   during the callback, even if IRQs are enabled. In fact, it would allow\n   IRQs to be enabled when releasing the lock. However, this feels like an\n   inelegant hack.\n3. Modify the interrupt handler to clear the RXPKTRDY flag if the request\n   queue is empty. While this approach also feels like a hack, it wastes\n   CPU time by attempting to handle incoming packets when the software is\n   not ready to process them.\n4. Flush the Rx FIFO instead of calling rxstate() in musb_ep_restart().\n   This ensures that the hardware can receive packets when there is at\n   least one request in the queue.

It targets the\nsame problem as the following downstream commit:\n\n  https://github.com/nxp-imx/linux-imx/commit/4e92355e1f79d225ea842511fcfd42b343b32995\n\nUnlike the downstream commit, this patch also resets the connected PCIe\ndevice if possible. Without this reset, certain drivers, such as ath10k\nor iwlwifi, will crash on resume. The device reset is also done by the\ndriver on other i.MX platforms, making this patch consistent with\nexisting practices.\n\nUpon resuming, the kernel will hang and display an error. Here\u0026apos;s an\nexample of the error encountered with the ath10k driver:\n\n  ath10k_pci 0000:01:00.0: Unable to change power state from D3hot to D0, device inaccessible\n  Unhandled fault: imprecise external abort (0x1406) at 0x0106f944\n\nWithout this patch, suspend/resume will fail on i.MX6QDL devices if a\nPCIe device is connected.\n\n[kwilczynski: commit log, added tag for stable releases](CVE-2024-57809)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\narm64: ptrace: fix partial SETREGSET for NT_ARM_TAGGED_ADDR_CTRL\n\nCurrently tagged_addr_ctrl_set() doesn\u0026apos;t initialize the temporary \u0026apos;ctrl\u0026apos;\nvariable, and a SETREGSET call with a length of zero will leave this\nuninitialized. Consequently tagged_addr_ctrl_set() will consume an\narbitrary value, potentially leaking up to 64 bits of memory from the\nkernel stack. The read is limited to a specific slot on the stack, and\nthe issue does not provide a write mechanism.\n\nAs set_tagged_addr_ctrl() only accepts values where bits [63:4] zero and\nrejects other values, a partial SETREGSET attempt will randomly succeed\nor fail depending on the value of the uninitialized value, and the\nexposure is significantly limited.\n\nFix this by initializing the temporary value before copying the regset\nfrom userspace, as for other regsets (e.g. NT_PRSTATUS, NT_PRFPREG,\nNT_ARM_SYSTEM_CALL). In the case of a zero-length write, the existing\nvalue of the tagged address ctrl will be retained.\n\nThe NT_ARM_TAGGED_ADDR_CTRL regset is only visible in the\nuser_aarch64_view used by a native AArch64 task to manipulate another\nnative AArch64 task. As get_tagged_addr_ctrl() only returns an error\nvalue when called for a compat task, tagged_addr_ctrl_get() and\ntagged_addr_ctrl_set() should never observe an error value from\nget_tagged_addr_ctrl(). Add a WARN_ON_ONCE() to both to indicate that\nsuch an error would be unexpected, and error handlnig is not missing in\neither case.(CVE-2024-57874)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nocfs2: fix slab-use-after-free due to dangling pointer dqi_priv\n\nWhen mounting ocfs2 and then remounting it as read-only, a\nslab-use-after-free occurs after the user uses a syscall to\nquota_getnextquota.  Specifically, sb_dqinfo(sb, type)-\u0026gt;dqi_priv is the\ndangling pointer.\n\nDuring the remounting process, the pointer dqi_priv is freed but is never\nset as null leaving it to be accessed.  Additionally, the read-only option\nfor remounting sets the DQUOT_SUSPENDED flag instead of setting the\nDQUOT_USAGE_ENABLED flags.

Those registers\nare XSAVE-managed, but they are \u0026quot;supervisor state components\u0026quot; which means\nthat userspace can not touch them with XSAVE/XRSTOR.  It also means that\nthey are not accessible from the existing ptrace ABI for XSAVE state.\nThus, there is a new ptrace get/set interface for it.\n\nThe regset code that ptrace uses provides an -\u0026gt;active() handler in\naddition to the get/set ones. For shadow stack this -\u0026gt;active() handler\nverifies that shadow stack is enabled via the ARCH_SHSTK_SHSTK bit in the\nthread struct. The -\u0026gt;active() handler is checked from some call sites of\nthe regset get/set handlers, but not the ptrace ones. This was not\nunderstood when shadow stack support was put in place.\n\nAs a result, both the set/get handlers can be called with\nXFEATURE_CET_USER in its init state, which would cause get_xsave_addr() to\nreturn NULL and trigger a WARN_ON(). The ssp_set() handler luckily has an\nssp_active() check to avoid surprising the kernel with shadow stack\nbehavior when the kernel is not ready for it (ARCH_SHSTK_SHSTK==0). That\ncheck just happened to avoid the warning.\n\nBut the -\u0026gt;get() side wasn\u0026apos;t so lucky. It can be called with shadow stacks\ndisabled, triggering the warning in practice, as reported by Christina\nSchimpe:\n\nWARNING: CPU: 5 PID: 1773 at arch/x86/kernel/fpu/regset.c:198 ssp_get+0x89/0xa0\n[...]\nCall Trace:\n\u0026lt;TASK\u0026gt;\n? show_regs+0x6e/0x80\n? ssp_get+0x89/0xa0\n? __warn+0x91/0x150\n? ssp_get+0x89/0xa0\n? report_bug+0x19d/0x1b0\n? handle_bug+0x46/0x80\n? exc_invalid_op+0x1d/0x80\n? asm_exc_invalid_op+0x1f/0x30\n? __pfx_ssp_get+0x10/0x10\n? ssp_get+0x89/0xa0\n? ssp_get+0x52/0xa0\n__regset_get+0xad/0xf0\ncopy_regset_to_user+0x52/0xc0\nptrace_regset+0x119/0x140\nptrace_request+0x13c/0x850\n? wait_task_inactive+0x142/0x1d0\n? do_syscall_64+0x6d/0x90\narch_ptrace+0x102/0x300\n[...]\n\nEnsure that shadow stacks are active in a thread before looking them up\nin the XSAVE buffer.
