CVE-2025-68793

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.16.0-1289896.2.zuul.bf4f11df81c1410bbe901c4373305a31

Description The Linux kernel contains a flaw in the DRM/amdgpu subsystem related to a use-after-free (UAF) condition during GPU recovery. This issue arises from a race between the sched timeout callback and the tdr work queue, potentially leading to a UAF when accessing the process address space ID (pasid). The vulnerability occurs when the tdr queue frees a job before the timeout callback completes, resulting in an invalid memory access. A KASAN trace is provided as an example of the issue.

Recommendations Update to version 6.16.0-1289896.2.zuul.bf4f11df81c1410bbe901c4373305a31 or later.
