How to Fix CVE-2026-68243

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-68243, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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)
