Summary
kernel security update
Details
The Linux Kernel, the operating system core itself.
Security Fix(es):
IEEE P802.11-REVme D1.1 through D7.0 allows FragAttacks against mesh networks. In mesh networks using Wi-Fi Protected Access (WPA, WPA2, or WPA3) or Wired Equivalent Privacy (WEP), an adversary can exploit this vulnerability to inject arbitrary frames towards devices that support receiving non-SSP A-MSDU frames. NOTE: this issue exists because of an incorrect fix for CVE-2020-24588. P802.11-REVme, as of early 2025, is a planned release of the 802.11 standard.(CVE-2025-27558)
In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: algif_aead - Revert to operating out-of-place\n\nThis mostly reverts commit 72548b093ee3 except for the copying of the associated data.\n\nThere is no benefit in operating in-place in algif_aead since the source and destination come from different mappings. Get rid of all the complexity added for in-place operation and just copy the AD directly.(CVE-2026-31431)
In the Linux kernel, the following vulnerability has been resolved:
media: mc, v4l2: serialize REINIT and REQBUFS with req_queue_mutex
MEDIA_REQUEST_IOC_REINIT can run concurrently with VIDIOC_REQBUFS(0) queue teardown paths. This can race request object cleanup against vb2 queue cancellation and lead to use-after-free reports.
We already serialize request queueing against STREAMON/OFF with req_queue_mutex. Extend that serialization to REQBUFS, and also take the same mutex in media_request_ioctl_reinit() so REINIT is in the same exclusion domain.
This keeps request cleanup and queue cancellation from running in parallel for request-capable devices.(CVE-2026-31473)
Severity
9.1 (Critical)

Title
crypto: algif_aead - Revert to operating out-of-place
Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: algif_aead - Revert to operating out-of-place
This mostly reverts commit 72548b093ee3 except for the copying of
the associated data.
There is no benefit in operating in-place in algif_aead since the
source and destination come from different mappings. Get rid of
all the complexity added for in-place operation and just copy the
AD directly.

Any race or SGL layout condition is attacker-controlled from the same process.\nPR:L - Creating and using AF_ALG AEAD sockets requires only an unprivileged local user on systems with CRYPTO_USER_API_AEAD enabled. The traced socket, bind, setsockopt, accept, sendmsg, and recvmsg paths do not require CAP_SYS_ADMIN or other real root privileges.\nUI:N - No victim interaction is needed once the attacker has local code execution. The attacker can open and drive the AF_ALG socket entirely through syscalls.\nS:U - The issue remains within the kernel/user crypto API security authority and does not cross a VM, IOMMU, or separate sandbox boundary. This is a standard local kernel attack surface.\nC:H - The removed in-place AEAD design used user-writable RX scatterlists as crypto source data and chained TX tag pages, creating a plausible decryption/authentication bypass for data protected by secret AEAD keys. Under the required uncertainty rule, this is scored as high confidentiality impact.\nI:H - The bug undermines AEAD authenticity by allowing source data used by the crypto operation to diverge from the data originally submitted and authenticated. This can allow forged or corrupted plaintext/ciphertext results, so integrity impact is high.\nA:H - The vulnerable path builds complex chained scatterlists from attacker-controlled local buffers and related AF_ALG fixes show these paths can lead to scatterwalk NULL dereferences and kernel panics. A local attacker can repeatedly trigger the operation, so availability impact is high."

In the Linux kernel, the following vulnerability has been resolved:
media: mc, v4l2: serialize REINIT and REQBUFS with req_queue_mutex
MEDIA_REQUEST_IOC_REINIT can run concurrently with VIDIOC_REQBUFS(0)
queue teardown paths. This can race request object cleanup against vb2
queue cancellation and lead to use-after-free reports.
We already serialize request queueing against STREAMON/OFF with
req_queue_mutex. Extend that serialization to REQBUFS, and also take
the same mutex in media_request_ioctl_reinit() so REINIT is in the
same exclusion domain.
This keeps request cleanup and queue cancellation from running in
parallel for request-capable devices.

{
"lang": "en",
"value": "AV:L - The vulnerable paths are reached through local `ioctl()` calls on media/video device file descriptors: `MEDIA_REQUEST_IOC_REINIT` on a request fd and `VIDIOC_REQBUFS(0)` on a V4L2 video fd. The affected code is not reachable directly from network packets or adjacent/physical protocol input.\nAC:L - This is a race, but an attacker controls both racing operations by issuing concurrent ioctls from local threads or processes. No condition beyond access to a request-capable media device is required.\nPR:L - The kernel path has no capability or admin check; the attacker only needs ordinary local ability to open the relevant `/dev/media*` and `/dev/video*` nodes. This is basic local privilege rather than real root/admin privilege.\nUI:N - Once the attacker can run local code and open the device nodes, exploitation is driven entirely by attacker-issued ioctls. No separate victim action is required.\nS:U - The vulnerability corrupts kernel media/videobuf2 request state within the same kernel security authority. It is not a VM escape, IOMMU bypass, or other cross-scope boundary violation.\nC:H - The bug is a use-after-free involving media request objects and vb2 buffer/request state during concurrent cleanup and queue teardown. Per kernel CVSS guidance, UAF memory corruption can be leveraged for kernel memory disclosure, so confidentiality impact is high.\nI:H - The race can corrupt freed kernel heap objects and request/buffer state, giving a plausible path to control-flow or arbitrary-write style exploitation. Per kernel CVSS guidance, use-after-free memory corruption warrants high integrity impact.\nA:H - The fix commit explicitly addresses use-after-free reports, and such kernel UAFs can reliably trigger KASAN reports, oopses, or panics. This is a high availability impact."
