CVE-2024-41092

Kernel memory corruption via fence revocation race

Published Jul 29, 2024 · Updated Aug 5, 2026

Use-after-free in Linux kernel i915 GGTT fencing from 5.8 allows local users with render-node access to corrupt kernel memory. i915_vma_revoke_fence calls fence_write without first waiting for fence->active to become idle, so completion callbacks can run while fence registers are revoked and reference freed i915 VMA or GEM objects. Reachability requires an Intel i915 GPU and low-privilege access to a DRM render node; exploitation supports kernel memory reads and writes, control-flow hijacking, or a full system crash.
