How to Fix CVE-2026-93136

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-2026-93136, 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: bus: mhi: ep: Fix device refcount leak in the error path of MHI device creation mhi_ep_create_device() takes one device reference for the UL channel and another for the DL channel after allocating the transfer device. These references are normally released by mhi_ep_destroy_device() before the device itself is removed. If dev_set_name() or device_add() fails, the error path currently drops only one reference. The remaining channel references keep the device from being released and leave the channels associated with a device that was never registered. Route both failures through a common unwind path that drops the DL channel reference, the UL channel reference, and the initial reference from device_initialize().
