Recommendation: Monitor — no exploitation signal at the moment.
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: NULL-check BO's backing store when determining GFX12 PTE flags
PRT BOs may not have any backing store, so bo->tbo.resource will be
NULL. Check for that before dereferencing.
