CVE-2025-38436 Details
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.
A vulnerability in the Linux kernel's Direct Rendering Manager (DRM) scheduler has been addressed. The issue arose when an entity from one application was terminated, leading to the improper signaling of scheduled fences for dependent jobs in another application. This mismanagement caused the dependent application to hang indefinitely, waiting for a resolution that would never come. The vulnerability has been fixed by ensuring that scheduled fences are correctly signaled when an entity is killed, allowing dependent applications to resume execution.
