Allowing scratch VMs through the ASID lookup also admits\ndma-fence mode VMs.\n\nIf such a VM faults on an already valid VMA, the handler reports success\nwithout fixing the fault, causing the GPU to retry indefinitely.\n\nOnly allow fault-mode VMs through the ASID lookup. Fault-mode VMs using\nscratch remain supported, while faults from 3D VMs are rejected.\n\n(cherry picked from commit bfb24a06405b652d37831f3fb66b71d33a6605de)","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/5e977521d21717edb8e91d004434697d6e3f248c","tags":[]},{"url":"https://git.kernel.org/stable/c/905d648e97ef3a291f71a935a7fab0133f27f0f7","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
