How to Fix CVE-2026-89870

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-2026-89870, 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: zoran: Avoid freeing a registered video_device twice zoran_init_video_device() installs zoran_vdev_release() as the video_device release callback through zoran_template. After video_register_device() succeeds, video_unregister_device() drops the registered video_device reference and the V4L2 core eventually invokes that release callback, which kfree()s the video_device. zoran_exit_video_devices() called video_unregister_device() and then kfree(zr->video_dev), so device teardown could free the same video_device twice. Remove the direct kfree() and clear the cached pointer after unregistering. The pre-registration failure path keeps its manual free because the video_device was not registered there. This issue was found by a static analysis checker and confirmed by manual source review.
