How to Fix CVE-2026-90080

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-2026-90080, 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: octeontx2-pf: fix NULL deref of af_xdp_zc_qidx on rep setup af_xdp_zc_qidx tracks receive queues using AF_XDP zero-copy and is allocated during PF/VF probe. Representors and other non-AF_XDP paths leave the pointer NULL, but several call sites used test_bit() on it unconditionally. Switching to devlink eswitch mode creates representors and runs otx2_init_hw_resources(), which reaches otx2_pool_aq_init() and oopses when dereferencing the NULL bitmap. Add NULL checks before every af_xdp_zc_qidx test_bit() use in the RSS, ethtool, XSK, and pool init paths.
