Detailed vulnerability description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to improper state management in the drm/xe exec queue suspend handling when invalidating userptr VMAs during GPU suspend in LR/preempt-fence VM mode. A local user can trigger userptr invalidation while the queue is treated as idle to cause a denial of service.
The issue can result in missed TLB invalidation and page faults during userptr invalidation tests.
