How to Fix CVE-2026-93040

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-2026-93040, 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: dmaengine: dw-edma: Serialize channel state checks pause() and resume() read and update channel state without holding vc.lock, while the interrupt handlers update the same state under it. Take the same lock around those state checks so that request, status, and configured stay consistent. For example, pause() can observe EDMA_ST_BUSY right before the interrupt handler completes the final descriptor and moves the channel to EDMA_ST_IDLE, and then record EDMA_REQ_PAUSE on an already idle channel. No further interrupt will acknowledge the request, and since issue_pending() requires EDMA_REQ_NONE, the channel is wedged for good: terminate_all() leaves the stale request behind, so even reconfiguring the channel does not recover it. issue_pending() already runs under vc.lock, but it tests configured before taking it. Move that test under the lock as well, so configured, request, and status are evaluated as one channel-state snapshot.
