DescriptionIn the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: actually validate userq BOs This was supposed to loop over the individual evicted list, as the kernel and always_valid evicted lists were already handled in amdgpu_vm_validate. Without this, BOs that were created and evicted before a userq was made would never end up in an eviction fence rearm. Also add the missing ref to the BO before drm_exec locks and refs it. (cherry picked from commit 18decfc9e8cc0fa70b6de9944cc27a37729edfbd)
