How to Fix CVE-2026-89874

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-2026-89874, 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: v4l2-async: avoid deleting unlinked ASC entry on link error v4l2_async_match_notify() creates ancillary media links before adding asc->asc_subdev_entry to sd->asc_list. If ancillary link creation fails, the function jumps to err_call_unbind while asc_subdev_entry has not been linked yet. Async connections are zero-allocated, so the list entry still has NULL next and prev pointers on this path. Calling list_del() on it can therefore dereference NULL instead of returning the original link creation error. Do not delete asc_subdev_entry from err_call_unbind. There is no list insertion to undo on this path; the bound callback and sub-device registration are the operations that need to be rolled back.
