How to Fix CVE-2026-93118

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-2026-93118, 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: usb: gadget: aspeed_udc: check endpoint DMA allocation ast_udc_probe() allocates a coherent DMA buffer used as the backing store for endpoint buffers. ast_udc_init_ep() derives per-endpoint buffer pointers from udc->ep0_buf, so a failed allocation is dereferenced during probe. Check the allocation before endpoint setup. The existing probe error path called ast_udc_remove(), which unregisters the gadget unconditionally and is not safe before usb_add_gadget_udc() succeeds. Add a local cleanup helper for probe failures so pre-registration failures only unwind the resources that were actually initialized. This was found by a local static analysis checker for unchecked allocator returns while scanning Linux 6.16. The change was checked by applying it to current mainline and by running checkpatch. I do not have access to Aspeed UDC hardware, so no runtime testing was performed.
