CVE-2026-90064

CVE-2026-90064 affects the Linux kernel drm/xe driver (Intel GPU). The root cause lies in the ASID lookup for page fault handling: scratch-enabled VMs that are not in fault mode—including dma-fence mode VMs—are incorrectly admitted. When such a VM faults on an already valid VMA, the handler repor...
