How to Fix CVE-2026-80940

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-2026-80940, 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: wifi: rtw88: pci: fix resource leak on failed NAPI setup rtw_pci_probe() allocates PCI resources through rtw_pci_setup_resource() before it sets up NAPI. If rtw_pci_napi_init() fails, the error path jumps straight to err_pci_declaim and skips rtw_pci_destroy(), leaving the PCI resources allocated by rtw_pci_setup_resource() behind. Add a dedicated cleanup label for the NAPI setup failure path so probe destroys the PCI resources. The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing current mainline kernels. The tool is still under development and is not yet publicly available. Manual inspection confirms that the bug is still present in v7.1-rc7. An x86_64 allyesconfig build showed no new warnings. As we do not have a suitable rtw88 PCI board to test with, no runtime testing was able to be performed.
