How to Fix CVE-2026-93042

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-2026-93042, 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: Terminate all descriptors without callbacks The DMA Engine client documentation says in the "Terminate APIs" section of Documentation/driver-api/dmaengine/client.rst: "No callback functions will be called for any incomplete transfers." dw-edma instead calls vchan_cookie_complete() when a deferred STOP reaches the interrupt handler. This schedules a callback for the active descriptor and leaves other issued or submitted descriptors queued. A late callback after dmaengine_terminate_sync() can dereference client state that has already been freed, while leftover descriptors may later restart into reused buffers or leak. Move all issued and submitted descriptors to the terminated list whenever termination completes. For a pending STOP, do this from both the DONE and ABORT paths. Complete their cookies in order without scheduling callbacks. A STOP can remain pending until the running transfer raises an interrupt. Make device_synchronize() wait for such a pending STOP to complete before releasing terminated descriptors. Reuse it from free_chan_resources(), then release the remaining virt-dma resources. Sleep instead of busy-polling while waiting, and warn if the existing timeout expires.
