In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: pin mqd and fw object bo to avoid eviction mqd and fw objects are queue core objects which should remain valid and never be unmapped and evicted for user queues to work properly. During eviction if these buffers are evicted the hw continue to use the invalid addresses and caused page faults and system hung.
