How to Fix CVE-2026-90322

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-2026-90322, 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: ocfs2/cluster: keep heartbeat local node stable o2nm_node_local_store() handles local=0 by stopping o2net and setting cl_local_node to O2NM_INVALID_NODE_NUM, but it leaves cl_has_local set. That stale state makes o2nm_this_node() return 255, blocks a later local=1 attempt with -EBUSY, and can feed 255 to heartbeat users that call o2nm_this_node() dynamically. Clearing cl_has_local is required when the local node is reset. But heartbeat threads can still be running at that point. They pin the local node config item at startup, yet o2hb_do_disk_heartbeat() and thread teardown re-read o2nm_this_node() for the local slot and for o2nm_undepend_this_node(). Once local=0 has cleared the live local-node state, those dynamic reads return O2NM_MAX_NODES, which is also the invalid node number 255. Store the local node number in the heartbeat region when the region starts. Use that stable node for heartbeat slot writes/checks, negotiation messages, and the final configfs undepend. Stop the heartbeat loop when the current local node no longer matches the stored node, and clear cl_has_local together with cl_local_node in the local=0 path so nodemanager state matches node removal.
