In the Linux kernel, the following vulnerability has been resolved:
drm/xe/guc_submit: add missing locking in wedged_fini
Any non-wedged queue can have a zero refcount here and can be running
concurrently with an async queue destroy, therefore dereferencing the
queue ptr to check wedge status after the lookup can trigger UAF if
queue is not wedged. Fix this by keeping the submission_state lock held
around the check to postpone the free and make the check safe, before
dropping again around the put() to avoid the deadlock.

CVE-2024-47738 Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Attila Szász discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2025-0927)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- ARM32 architecture;
- ARM64 architecture;
- PowerPC architecture;
- RISC-V architecture;
- S390 architecture;
