Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

nfc: nci: Fix uninit-value in nci_rx_work

syzbot reported the following uninit-value access issue [1]

nci_rx_work() parses received packet from ndev->rx_q. It should be validated header size, payload size and total packet size before processing the packet. If an invalid packet is detected, it should be silently discarded.(CVE-2024-38381)

In the Linux kernel, the following vulnerability has been resolved:net: ti: icssg_prueth: Fix NULL pointer dereference in prueth_probe()In the prueth_probe() function, if one of the calls to emac_phy_connect()fails due to of_phy_connect() returning NULL, then the subsequent call tophy_attached_info() will dereference a NULL pointer.Check the return code of emac_phy_connect and fail cleanly if there is anerror.(CVE-2024-38584)

In the Linux kernel, the following vulnerability has been resolved:cpufreq: exit() callback is optionalThe exit() callback is optional and shouldn t be called without checkinga valid pointer first.Also, we must clear freq_table pointer even if the exit() callback isn tpresent.(CVE-2024-38615)

In the Linux kernel, the following vulnerability has been resolved:serial: max3100: Update uart_driver_registered on driver removalThe removal of the last MAX3100 device triggers the removal ofthe driver. However, code doesn t update the respective globalvariable and after insmod — rmmod — insmod cycle the kerneloopses: max3100 spi-PRP0001:01: max3100_probe: adding port 0 BUG: kernel NULL pointer dereference, address: 0000000000000408 ...

Instead of clearing itmove the assignment after the successfull uart_register_driver() call.(CVE-2024-38633)

In the Linux kernel, the following vulnerability has been resolved:

enic: Validate length of nl attributes in enic_set_vf_port

enic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILE is of length PORT_PROFILE_MAX and that the nl attributes IFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX. These attributes are validated (in the function do_setlink in rtnetlink.c) using the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILE as NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY and IFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validation using the policy is for the max size of the attributes and not on exact size so the length of these attributes might be less than the sizes that enic_set_vf_port expects. This might cause an out of bands read access in the memcpys of the data of these attributes in enic_set_vf_port.(CVE-2024-38659)

In the Linux kernel, the following vulnerability has been resolved:riscv: prevent pt_regs corruption for secondary idle threadsTop of the kernel thread stack should be reserved for pt_regs. Howeverthis is not the case for the idle threads of the secondary boot harts.Their stacks overlap with their pt_regs, so both may get corrupted.Similar issue has been fixed for the primary hart, see c7cdd96eca28( riscv: prevent stack corruption by reserving task_pt_regs(p) early ).However that fix was not propagated to the secondary harts. The problemhas been noticed in some CPU hotplug tests with V enabled. The functionsmp_callin stored several registers on stack, corrupting top of pt_regsstructure including status field. As a result, kernel attempted to saveor restore inexistent V context.(CVE-2024-38667)

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: fix null-ptr-deref in block_touch_buffer tracepoint

Patch series "nilfs2: fix null-ptr-deref bugs on block tracepoints".

This series fixes null pointer dereference bugs that occur when using nilfs2 and two block-related tracepoints.

This patch (of 2):

It has been reported that when using "block:block_touch_buffer" tracepoint, touch_buffer() called from __nilfs_get_folio_block() causes a NULL pointer dereference, or a general protection fault when KASAN is enabled.

This happens because since the tracepoint was added in touch_buffer(), it references the dev_t member bh->b_bdev->bd_dev regardless of whether the buffer head has a pointer to a block_device structure. In the current implementation, the block_device structure is set after the function returns to the caller.

Here, touch_buffer() is used to mark the folio/page that owns the buffer head as accessed, but the common search helper for folio/page used by the caller function was optimized to mark the folio/page as accessed when it was reimplemented a long time ago, eliminating the need to call touch_buffer() here in the first place.

So this solves the issue by eliminating the touch_buffer() call itself.(CVE-2024-53131)

In the Linux kernel, the following vulnerability has been resolved:drm: adv7511: Fix use-after-free in adv7533_attach_dsi()The host_node pointer was assigned and freed in adv7533_parse_dt(), andlater, adv7533_attach_dsi() uses the same. Fix this use-after-free issueby dropping of_node_put() in adv7533_parse_dt() and calling of_node_put()in error path of probe() and also in the remove().(CVE-2024-57887)

In the Linux kernel, the following vulnerability has been resolved:

nfsd: put dl_stid if fail to queue dl_recall

Before calling nfsd4_run_cb to queue dl_recall to the callback_wq, we increment the reference count of dl_stid. We expect that after the corresponding work_struct is processed, the reference count of dl_stid will be decremented through the callback function nfsd4_cb_recall_release. However, if the call to nfsd4_run_cb fails, the incremented reference count of dl_stid will not be decremented correspondingly, leading to the following nfs4_stid leak: unreferenced object 0xffff88812067b578 (size 344): comm "nfsd", pid 2761, jiffies 4295044002 (age 5541.241s) hex dump (first 32 bytes): 01 00 00 00 6b 6b 6b 6b b8 02 c0 e2 81 88 ff ff ....kkkk........ 00 6b 6b 6b 6b 6b 6b 6b 00 00 00 00 ad 4e ad de .kkkkkkk.....N.. backtrace: kmem_cache_alloc+0x4b9/0x700 nfsd4_process_open1+0x34/0x300 nfsd4_open+0x2d1/0x9d0 nfsd4_proc_compound+0x7a2/0xe30 nfsd_dispatch+0x241/0x3e0 svc_process_common+0x5d3/0xcc0 svc_process+0x2a3/0x320 nfsd+0x180/0x2e0 kthread+0x199/0x1d0 ret_from_fork+0x30/0x50 ret_from_fork_asm+0x1b/0x30 unreferenced object 0xffff8881499f4d28 (size 368): comm "nfsd", pid 2761, jiffies 4295044005 (age 5541.239s) hex dump (first 32 bytes): 01 00 00 00 00 00 00 00 30 4d 9f 49 81 88 ff ff ........0M.I.... 30 4d 9f 49 81 88 ff ff 20 00 00 00 01 00 00 00 0M.I.... ....... backtrace: kmem_cache_alloc+0x4b9/0x700 nfs4_alloc_stid+0x29/0x210 alloc_init_deleg+0x92/0x2e0 nfs4_set_delegation+0x284/0xc00 nfs4_open_delegation+0x216/0x3f0 nfsd4_process_open2+0x2b3/0xee0 nfsd4_open+0x770/0x9d0 nfsd4_proc_compound+0x7a2/0xe30 nfsd_dispatch+0x241/0x3e0 svc_process_common+0x5d3/0xcc0 svc_process+0x2a3/0x320 nfsd+0x180/0x2e0 kthread+0x199/0x1d0 ret_from_fork+0x30/0x50 ret_from_fork_asm+0x1b/0x30 Fix it by checking the result of nfsd4_run_cb and call nfs4_put_stid if fail to queue dl_recall.(CVE-2025-22025)

wifi: cfg80211: fix out-of-bounds access during multi-link element defragmentation

Currently during the multi-link element defragmentation process, the multi-link element length added to the total IEs length when calculating the length of remaining IEs after the multi-link element in cfg80211_defrag_mle(). This could lead to out-of-bounds access if the multi-link element or its corresponding fragment elements are the last elements in the IEs buffer.

To address this issue, correctly calculate the remaining IEs length by deducting the multi-link element end offset from total IEs end offset.(CVE-2025-37973)

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB) invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing memory protections or escalating privileges. (CVE-2025-10263)
