CVE-2026-68382

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

Description An issue exists in the drm/xe/guc component where GuC exec queue destruction can occur asynchronously. If the final device put is executed from a destroy worker, the drmm cleanup process may attempt to drain the same workqueue, resulting in a deadlock. This is addressed by maintaining a drm device reference for the duration of the queue lifetime and releasing it only after the queue teardown is complete, preventing drmm cleanup from executing while asynchronous destroy work is pending.

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