CVE の説明
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix dc_lock leak on GPU reset error paths
On GPU reset, dm_suspend() takes dc_lock and leaves it for dm_resume()
to drop. If amdgpu_dm_commit_zero_streams() or dm_dmub_hw_init() fails,
the function returns with the lock still held. The matching resume path
is then skipped, so every later dc_lock take hangs.
Release the cached DC state and unlock before returning the error.
