Kernel crash via evicted DPT page tables
Published Sep 18, 2025 · Updated Sep 18, 2025
Denial of service in the i915 DPT code in Linux 6.0 through 6.1.22 and 6.2 through 6.2.9 allows local users to crash the kernel during hibernation. i915_gem_object_is_framebuffer() fails to classify the DPT backing object as a framebuffer, so the shrinker can evict it while the framebuffer remains bound and hibernation later rewrites page-table entries in the evicted object. Exploitation requires local low-privileged access, an affected Intel i915 display configuration using regular shared memory for the DPT, and entry into hibernation; the documented consequence is an immediate kernel oops.
