drm/i915/gem: Fix NULL deref in I915_CONTEXT_PARAM_SSEU

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 2b56757a9a7456825eb668fde92299e01c5e2721, 726f27bca93e6c83b263542669132ee1d0eb693e, 97a4872ef927dee301d76085cb19f6e36d4a53a4; azl3 kernel 6.6.143.1-1 on Azure Linux 3.0 6.6.150.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 2b56757a9a7456825eb668fde92299e01c5e2721, 726f27bca93e6c83b263542669132ee1d0eb693e, 97a4872ef927dee301d76085cb19f6e36d4a53a4; azl3 kernel 6.6.143.1-1 on Azure Linux 3.0 6.6.150.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Fix NULL deref in I915_CONTEXT_PARAM_SSEU Setting context engine slot N into I915_ENGINE_CLASS_INVALID / I915_ENGINE_CLASS_INVALID_NONE and attempting to apply I915_CONTEXT_PARAM_SSEU to the same slot N will deref NULL. Fix that. Discovered using AI-assisted static analysis confirmed by Intel Product Security. (cherry picked from commit 36eda5b5c2d40da41cc0a5403c26986237cf9e87)

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
