CVE-2026-72452

Local kernel compromise via stale color-blob pointers

Published Aug 15, 2026 · Updated Aug 15, 2026

Memory corruption in affected Linux kernels allows local users to compromise the kernel through atomic display commits to drm/i915. The intel_crtc_put_color_blobs() function drops CRTC color-blob references without clearing their pointers, so a later error cleanup drops the same references again. Exploitation requires DRM-master access, color blobs, an active DisplayPort tunnel, and concurrent atomic requests; the double free exposes kernel memory corruption capable of a system crash or kernel-memory read, write, and code execution.
