How to Fix CVE-2026-89463

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-2026-89463, 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: power: supply: ucs1002: fix use-after-free on remove ucs1002 has no remove callback, so unbind runs entirely through devm. The alert IRQ handler queues the health_poll delayed work, and the work reschedules itself while the chip reports a bad-health condition. devm frees the alert IRQ, which only synchronizes the handler; it does not cancel the delayed work, which can then run after devm frees the driver data and dereference it. Register health_poll with devm_delayed_work_autocancel() before the alert IRQ is requested. devm then frees the IRQ before cancelling the work, so the handler can no longer queue it and the work is cancelled before the driver data is freed. This issue was found by an in-house static analysis tool.
