CVE-2025-38436

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, drmschedentitykill() removes all jobs belonging to that entity through drmschedentitykilljobswork(). 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.
