# CVE-2025-38436: drm/scheduler: signal scheduled fence when kill job

Status: published. Published: 2025-07-25. Updated: 2026-11-05.

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

drm/scheduler: signal scheduled fence when kill job

When an entity from application B is killed, drm_sched_entity_kill()
removes all jobs belonging to that entity through
drm_sched_entity_kill_jobs_work(). If application A's job depends on a
scheduled fence from application B's job, and that fence is not properly
signaled during the killing process, application A's dependency cannot be
cleared.

This leads to application A hanging indefinitely while waiting for a
dependency that will never be resolved. Fix this issue by ensuring that
scheduled fences are properly signaled when an entity is killed, allowing
dependent applications to continue execution.
