How to Fix CVE-2026-72307

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-2026-72307, 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: mlxsw: fix refcount leak in mlxsw_sp_vrs_lpm_tree_replace() When mlxsw_sp_vrs_lpm_tree_replace() fails after replacing some VRs, the error rollback loop does not correctly revert the preceding replacements. The loop decrements the index but fails to update the vr pointer, which still points to the VR that caused the failure. As a result, the condition and the rollback call always operate on the same VR, potentially calling mlxsw_sp_vr_lpm_tree_replace() multiple times on it while never rolling back the earlier VRs. Those VRs continue to hold a reference to new_tree acquired via mlxsw_sp_lpm_tree_hold(), leaking the reference count of new_tree. Fix by reinitializing vr inside the error loop with the updated index: vr = &mlxsw_sp->router->vrs[i]; so that the loop correctly iterates over all VRs that were actually replaced.
