CVE-2026-68273

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description Issues exist in the context pstate handling code within the drm/amdgpu component. The most critical problems include potential use-after-free and NULL pointer dereferences during context initialization. These occur because the amdgpu ctx init() function fails to hold the adev->pm.stable pstate ctx lock, which is required when modifying or clearing the stored context pointer via sysfs or context code. Additionally, the context fini process can overwrite pstate configurations set via sysfs because the restore state ctx->stable pstate is saved at context initialization rather than when the pstate actually changes, leading to incorrect restoration upon context exit.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
