Technical Description
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)
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version.
