CVE-2026-68383

HighCVSS 7.8/10Last modified Oct 21, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

drm/xe/guc: Keep scheduler timeline name alive

The scheduler keeps a pointer to the timeline name, but q->name is freed with the exec queue while scheduler fences can still reference it.

Store the name in struct xe_guc_exec_queue so it shares the scheduler's RCU-deferred lifetime.

(cherry picked from commit 41075f0eb5dcbd3b065d15f15ef7bbe9315188e8)
