Integrity High (I:H)
Availability High (A:H)

How to Fix CVE-2026-93806

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-2026-93806, 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: validate assoc response length before status and IE access cfg80211_rx_assoc_resp() initialises the status and response-IE fields of cfg80211_connect_resp_params from the management frame before proving that the frame is long enough for those offsets. S1G and regular association responses also have different IE offsets, but the S1G path only patched resp_ie after the unsafe initialiser had already run. Defer resp_ie, resp_ie_len, and status to after the link-iteration loop. Use a bool to remember whether the frame is S1G, then validate the appropriate minimum length and set all three fields in a single if/else block. Funnel short-frame and SME-reject cleanup through a shared free_bss label for the abandon paths.
