How to Fix CVE-2026-89871

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-2026-89871, 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: media: video-i2c: fix kthread error pointer left in kthread_vid_cap on failure kthread_run() returns an ERR_PTR on failure, not NULL. When start_streaming() fails, data->kthread_vid_cap is left holding this error pointer instead of being cleared. This causes two subsequent bugs: 1. A future call to start_streaming() sees a non-NULL kthread_vid_cap and returns 0 (success) immediately, without actually starting the capture thread. 2. A call to stop_streaming() checks 'kthread_vid_cap == NULL' which is false for an error pointer, and proceeds to call kthread_stop() on the error pointer, leading to a kernel crash. Fix this by resetting kthread_vid_cap to NULL on failure before jumping to the error path.
