How to Fix CVE-2026-90121

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-2026-90121, 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: irqchip/gic-v5: Clear per-CPU IRS data on teardown IRS affinity setup publishes an IRS pointer and IAFFID state in the per-CPU data before the remaining IRS initialization can fail. The error path then frees the IRS data without clearing that published state, leaving CPUs associated with freed memory. On initialization failure and normal IRS teardown, clear the per-CPU IRS association by removing the stale pointer to irs_data. Also invalidate the per-CPU IAFFID state for any CPUs that were tied to the IRS before it was freed.
