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)
