CVE-2025-38436 Information

Jul 26, 2025 cve

Description

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.
