Integrity High (I:H)
Availability High (A:H)

How to Fix CVE-2026-89522

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-2026-89522, 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: staging/ipu7: fix async notifier UAF on probe error path isys_register_devices() registers the V4L2 async notifier via isys_notifier_init(). If a subsequent probe step such as isys_fw_log_init() fails, isys_probe() jumps to the out_cleanup label which only calls isys_unregister_devices(). That helper tears down the video devices, subdevices, V4L2 device and media device, but never unregisters or cleans up the async notifier. As a result the notifier stays chained in the global notifier_list while the enclosing struct ipu7_isys is freed by devres, leading to list corruption and a use-after-free the next time the list is walked. The remove path already does the right thing by calling isys_notifier_cleanup() before isys_unregister_devices(). Mirror that on the probe error path so the notifier is unregistered and cleaned up before the device is torn down.
