Description
A vulnerability in the Linux kernel's drm/amdkfd component related to CRIU restore was fixed by properly acquiring queue buffers. The issue was that set_queue_properties_from_criu() did not fill out buffer fields in queue_properties, which could cause problems when subsequent code expected these fields to be non-null. The fix involved adding the correct call to kfd_queue_acquire_buffers() and correcting cast types.
