In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: csa unmap use uninterruptible lock
After process exit to unmap csa and free GPU vm, if signal is accepted and then waiting to take vm lock is interrupted and return, it causes memory leaking and below warning backtrace.
Change to use uninterruptible wait lock fix the issue.
