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

drm/xe: Fix memory leak in exec_queue_set_hang_replay_state()

The q->replay_state is blindly overwritten, which can potentially leak memory that was previously allocated by vmemdup_user(). Return an error if q->replay_state is not empty.

Discovered using AI-assisted static analysis confirmed by Intel Product Security.
