CVE-2026-90064 in Linux
요약
\~에 의해 MITRE • 2026. 09. 17.
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Reject page faults from non-fault-mode scratch VMs
Having scratch enabled does not make a VM capable of handling recoverable page faults. Allowing scratch VMs through the ASID lookup also admits dma-fence mode VMs.
If such a VM faults on an already valid VMA, the handler reports success without fixing the fault, causing the GPU to retry indefinitely.
Only allow fault-mode VMs through the ASID lookup. Fault-mode VMs using scratch remain supported, while faults from 3D VMs are rejected.
(cherry picked from commit bfb24a06405b652d37831f3fb66b71d33a6605de)
