In the Linux kernel, the following vulnerability has been resolved:
Revert "drm/amd: Check if ASPM is enabled from PCIe subsystem"
This reverts commit 7294863a6f01248d72b61d38478978d638641bee.
This commit was erroneously applied again after commit 0ab5d711ec74
("drm/amd: Refactor `amdgpu_aspm` to be evaluated per device")
removed it, leading to very hard to debug crashes, when used with a system with two
AMD GPUs of which only one supports ASPM.
(cherry picked from commit 97a9689300eb2b393ba5efc17c8e5db835917080)

CVE-2026-43314 [HIGH] Linux kernel (Xilinx) vulnerabilities
Title: Linux kernel (Xilinx) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the Linux kernel algif_aead module did not properly
handle in-place cryptographic operations. This flaw is known as Copy Fail.
A local attacker could use this to escalate privileges, or possibly escape
a container. (CVE-2026-31431)
It was discovered that the Linux kernel did not properly handle shared page
fragments during socket buffer operations, collectively known as Dirty
Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the
RxRPC networking subsystem when processing paged fragments. A local
attacker could use this to escalate privileges, or possibly escape a
container. (CVE-2026-43284, CVE-2026-43500, CVE-2026-45998, CVE-2026-46000)
