CVE-2026-72452
CVE-2026-72452 is a security vulnerability in Kernel. O3 Security confirms whether CVE-2026-72452 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
drm/i915: clear CRTC color blob pointers after dropping refs
Real-World Exposure
KernelReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Linux packages — download data is not available via public APIs for these ecosystems.
Description
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: clear CRTC color blob pointers after dropping refs
intel_crtc_put_color_blobs() drops the CRTC color blob references, but leaves the corresponding pointers unchanged.
This can matter in intel_crtc_prepare_cleared_state(), which frees the old CRTC hw state before calling intel_dp_tunnel_atomic_clear_stream_bw(). The latter can fail while looking up the DP tunnel group state, for example with -EDEADLK.
If that happens, the function returns without completing the cleared state preparation. The failed atomic state will then be cleared by the atomic core and intel_crtc_free_hw_state() can be called again for the same state, dropping the same blob references again.
Clear the blob pointers after dropping the references so repeated cleanup of the same CRTC hw state is safe.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Kernel. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update Kernel to 6.12.97 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-72452 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-72452 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-72452. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
