How to Fix CVE-2026-90292

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-2026-90292, 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: RDMA/siw: Fix use-after-free in siw_accept() siw_accept() looks up the QP supplied by userspace. If that QP is already in RTS, the function jumps to error cleanup before associating the incoming CEP with it. The cleanup tests whether qp->cep is non-NULL and assumes the current call installed the association. However, qp->cep can point to the CEP of an existing connection. The cleanup then drops a reference from the incoming cep, not qp->cep. Once the incoming endpoint loses its remaining references, this can free it before the subsequent cep->qp store, causing a use-after-free. It also clears the existing QP association. Only release the association reference when qp->cep is the incoming CEP. This preserves an existing association and avoids accessing the freed endpoint.
