How to Fix CVE-2026-93120

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-2026-93120, 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: configfs: fix out-of-bounds read of qw_sign os_desc_qw_sign_show() passes OS_STRING_QW_SIGN_LEN as the input length to utf16s_to_utf8s(), but that argument counts UTF-16 code units while OS_STRING_QW_SIGN_LEN (14) is the byte size of qw_sign[]. The array holds only OS_STRING_QW_SIGN_LEN / 2 (7) code units, so the conversion reads up to 7 units (14 bytes) past the end of qw_sign[] into the following members of struct gadget_info when the stored signature fills the array without a NUL terminator, exposing those bytes through the configfs attribute. The store path halves the count for its input bound but passes the full byte count as the utf8s_to_utf16s() output limit; use the destination code-unit count in both directions.
