CVE-2023-52913

Local kernel crash via i915 context use-after-free

Published Aug 21, 2024 · Updated Aug 5, 2026

Use-after-free in the Linux kernel's i915 DRM driver allows local users to crash the system by racing graphics-context destruction. gem_context_register() publishes a context in an xarray before its final pointer use, allowing a parallel I915_GEM_CONTEXT_DESTROY ioctl to free it first. Low-privileged local access and concurrent ioctl timing are required; the reported availability consequence is a kernel crash.
