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

drm/amdgpu/userq: fix access to stale wptr mapping

Use drm_exec to take both locks i.e vm root bo and

wptr_obj bo to access the mapping data properly.

This fixes the security issue of unmap the wptr_obj while

a queue creation is in progress and passing other

bo at same address.

(cherry picked from commit 1fc6c8ab45dbee096469c08c13f6099d57a52d6c) (NVD)
