How to Fix CVE-2026-90343

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-2026-90343, 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: cfg80211: stop PMSR before P2P and NAN teardown PMSR request teardown must abort active measurements while the wireless_dev is still present in the driver. cfg80211_leave_locked() and cfg80211_stop_pd() already do this before invoking the driver's stop callback, but cfg80211_stop_p2p_device() and cfg80211_stop_nan() do not. Those helpers are also called directly by nl80211, rfkill shutdown, and wireless_dev unregister paths. If one of these paths stops a P2P device or NAN interface with a pending request, it removes the mac80211 subinterface from the driver first. Subsequent request cleanup cannot reach the lower driver's abort callback, but cfg80211 frees the request regardless. Driver state can then retain a stale request and use it when it later reports a result. Call cfg80211_pmsr_wdev_down() before stopping the P2P device or NAN interface. This keeps lower-driver request state and cfg80211 request ownership in sync for all of the helpers' callers.
