Specifically, a VMA which has a valid pointer to vma->vm_userfaultfd_ctx, but no UFFD flags in vma->vm_flags. The inconsistency is caused in ksm_madvise(): when user calls madvise() with MADV_UNMEARGEABLE on a VMA that is registered for UFFD in MINOR mode, it accidentally clears all flags stored in the upper 32 bits of vma->vm_flags. Assuming x86_64 kernel build, unsigned long is 64-bit and unsigned int and int are 32-bit wide. This setup causes the following mishap during the &= ~VM_MERGEABLE assignment. VM_MERGEABLE is a 32-bit constant of type unsigned int, 0x8000'0000. After ~ is applied, it becomes 0x7fff'ffff unsigned int, which is then promoted to unsigned long before the & operation. This promotion fills upper 32 bits with leading 0s, as we're doing unsigned conversion (and even for a signed conversion, this wouldn't help as the leading bit is 0). & operation thus ends up AND-ing vm_flags with 0x0000'0000'7fff'ffff instead of intended 0xffff'ffff'7fff'ffff and hence accidentally clears the upper 32-bits of its value. Fix it by changing VM_MERGEABLE constant to unsigned long, using the BIT() macro. Note: other VM* flags are not affected: This only happens to the VM_MERGEABLE flag, as the other VM* flags are all constants of type int and after ~ operation, they end up with leading 1 and are thus converted to unsigned long with leading 1s. Note 2: After commit 31defc3b01d9 ("userfaultfd: remove (VM)BUG_ON()s"), this is no longer a kernel BUG, but a WARNING at the same place: [ 45.595973] WARNING: CPU: 1 PID: 2474 at mm/userfaultfd.c:2067 but the root-cause (flag-drop) remains the same.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:tcp_metrics: validate source addr lengthI don t see anything checking that TCP_METRICS_ATTR_SADDR_IPV4is at least 4 bytes long, and the policy doesn t have an entryfor this attribute at all (neither does it for IPv6 but v6 ismanually validated).(CVE-2024-42154)

In the Linux kernel, the following vulnerability has been resolved:resource: fix region_intersects() vs add_memory_driver_managed()On a system with CXL memory, the resource tree (/proc/iomem) related toCXL memory may look like something as follows.490000000-50fffffff : CXL Window 0 490000000-50fffffff : region0 490000000-50fffffff : dax0.0 490000000-50fffffff : System RAM (kmem)Because drivers/dax/kmem.c calls add_memory_driver_managed() duringonlining CXL memory, which makes System RAM (kmem) a descendant of CXLWindow X . This confuses region_intersects(), which expects all SystemRAM resources to be at the top level of iomem_resource. This can lead tobugs.For example, when the following command line is executed to write somememory in CXL memory range via /dev/mem, $ dd if=data of=/dev/mem bs=$((1 << 10)) seek=$((0x490000000 >> 10)) count=1 dd: error writing /dev/mem : Bad address 1+0 records in 0+0 records out 0 bytes copied, 0.0283507 s, 0.0 kB/sthe command fails as expected. However, the error code is wrong. Itshould be Operation not permitted instead of Bad address . Moreseriously, the /dev/mem permission checking in devmem_is_allowed() passesincorrectly. Although the accessing is prevented later because ioremap()isn t allowed to map system RAM, it is a potential security issue. Duringcommand executing, the following warning is reported in the kernel log forcalling ioremap() on system RAM. ioremap on RAM at 0x0000000490000000 - 0x0000000490000fff WARNING: CPU: 2 PID: 416 at arch/x86/mm/ioremap.c:216 __ioremap_caller.constprop.0+0x131/0x35d Call Trace: memremap+0xcb/0x184 xlate_dev_mem_ptr+0x25/0x2f write_mem+0x94/0xfb vfs_write+0x128/0x26d ksys_write+0xac/0xfe do_syscall_64+0x9a/0xfd entry_SYSCALL_64_after_hwframe+0x4b/0x53The details of command execution process are as follows. In the aboveresource tree, System RAM is a descendant of CXL Window 0 instead of atop level resource. So, region_intersects() will report no System RAMresources in the CXL memory region incorrectly, because it only checks thetop level resources. Consequently, devmem_is_allowed() will return 1(allow access via /dev/mem) for CXL memory region incorrectly. Fortunately, ioremap() doesn t allow to map System RAM and reject theaccess.So, region_intersects() needs to be fixed to work correctly with theresource tree with System RAM not at top level as above. To fix it, ifwe found a unmatched resource in the top level, we will continue to searchmatched resources in its descendant resources. So, we will not miss anymatched resources in resource tree anymore.In the new implementation, an example resource tree|------------- CXL Window 0 ------------||-- System RAM --|will behave similar as the following fake resource tree forregion_intersects(, IORESOURCE_SYSTEM_RAM, ),|-- System RAM --||-- CXL Window 0a --|Where CXL Window 0a is part of the original CXL Window 0 thatisn t covered by System RAM .(CVE-2024-49878)

usb: xhci: Apply the link chain quirk on NEC isoc endpoints

Two clearly different specimens of NEC uPD720200 (one with start/stop bug, one without) were seen to cause IOMMU faults after some Missed Service Errors. Faulting address is immediately after a transfer ring segment and patched dynamic debug messages revealed that the MSE was received when waiting for a TD near the end of that segment:

[ 1.041954] xhci_hcd: Miss service interval error for slot 1 ep 2 expected TD DMA ffa08fe0 [ 1.042120] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09000 flags=0x0000] [ 1.042146] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09040 flags=0x0000]

It gets even funnier if the next page is a ring segment accessible to the HC. Below, it reports MSE in segment at ff1e8000, plows through a zero-filled page at ff1e9000 and starts reporting events for TRBs in page at ff1ea000 every microframe, instead of jumping to seg ff1e6000.

It's possible that data from the isochronous device were written to random buffers of pending TDs on other endpoints (either IN or OUT), other devices or even other HCs in the same IOMMU domain.

Lastly, an error from a different USB device on another HC. Was it caused by the above? I don't know, but it may have been. The disk was working without any other issues and generated PCIe traffic to starve the NEC of upstream BW and trigger those MSEs. The two HCs shared one x1 slot by means of a commercial "PCIe splitter" board.

Fortunately, it appears that this ridiculous bug is avoided by setting the chain bit of Link TRBs on isochronous rings. Other ancient HCs are known which also expect the bit to be set and they ignore Link TRBs if it's not. Reportedly, 0.95 spec guaranteed that the bit is set.

The bandwidth-starved NEC HC running a 32KB/uframe UVC endpoint reports tens of MSEs per second and runs into the bug within seconds.…

Kernel panics because it detects UFFD inconsistency during userfaultfd_release_all(). Specifically, a VMA which has a valid pointer to vma->vm_userfaultfd_ctx, but no UFFD flags in vma->vm_flags.

The inconsistency is caused in ksm_madvise(): when user calls madvise() with MADV_UNMEARGEABLE on a VMA that is registered for UFFD in MINOR mode, it accidentally clears all flags stored in the upper 32 bits of vma->vm_flags.

Assuming x86_64 kernel build, unsigned long is 64-bit and unsigned int and int are 32-bit wide. This setup causes the following mishap during the &= ~VM_MERGEABLE assignment.

VM_MERGEABLE is a 32-bit constant of type unsigned int, 0x8000'0000. After ~ is applied, it becomes 0x7fff'ffff unsigned int, which is then promoted to unsigned long before the & operation. This promotion fills upper 32 bits with leading 0s, as we're doing unsigned conversion (and even for a signed conversion, this wouldn't help as the leading bit is 0). & operation thus ends up AND-ing vm_flags with 0x0000'0000'7fff'ffff instead of intended 0xffff'ffff'7fff'ffff and hence accidentally clears the upper 32-bits of its value.

Fix it by changing VM_MERGEABLE constant to unsigned long, using the BIT() macro.

Note: other VM_* flags are not affected: This only happens to the VM_MERGEABLE flag, as the other VM_* flags are all constants of type int and after ~ operation, they end up with leading 1 and are thus converted to unsigned long with leading 1s.

Note 2: After commit 31defc3b01d9 ("userfaultfd: remove (VM_)BUG_ON()s"), this is no longer a kernel BUG, but a WARNING at the same place:

[ 45.595973] WARNING: CPU: 1 PID: 2474 at mm/userfaultfd.c:2067

but the root-cause (flag-drop) remains the same.

Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM). An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege escalation, or possibly escape a container.
