How to Fix CVE-2026-97436

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-2026-97436, 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: dpaa2-switch: rework FDB management on the bridge leave path On bridge leave, the dpaa2_switch_port_set_fdb() function always allocates a new FDB for the port which is becoming standalone. In case no FDB is found, then the port leaving a bridge will continue to use the current one. The above logic does not cover the case in which there are multiple bridges which have ports from the same DPSW instance. In this case, when the last port leaves bridge #1, it finds an unused FDB to switch to, but the old FDB is not marked as unused. Since the number of FDBs is equal to the number of DPSW interfaces, this will eventually lead to multiple ports sharing the same FDB. Fix this by changing how we are managing the FDBs on the leave path. Instead of directly allocating a new FDB, first verify if the current port is the last one to leave a bridge. If this is the case, then continue to use the current FDB and only allocate another FDB if there are other ports remaining in the bridge.
