CVE-2026-68383

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

Description A memory management issue exists in the drm/xe/guc component where the scheduler maintains a pointer to the timeline name. However, q->name is freed along with the exec queue while scheduler fences may still reference it. This occurs because the name is not properly tied to the scheduler's RCU-deferred lifetime, where RCU (Read-Copy-Update) is a synchronization mechanism used to protect shared data from simultaneous access.

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