How to Fix CVE-2026-90230

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-2026-90230, 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: nvmet: fix heap out-of-bounds read in nvmet_auth_negotiate() nvmet_execute_auth_send() allocates the DH-HMAC-CHAP message buffer with the host-supplied transfer length (tl) and hands it to nvmet_auth_negotiate() without passing tl along. nvmet_auth_negotiate() then reads the negotiate header and, for each of the halen hash identifiers and dhlen DH group identifiers, indexes into the fixed idlist[60] array (hashes at idlist[0..halen), groups at idlist[30..]). Neither the transfer length nor halen/dhlen is validated. A malicious or non-conformant host can report a tl smaller than the negotiate structure, or a halen/dhlen larger than the array (both are u8, up to 255), making the loops read past the end of the allocated buffer (heap out-of-bounds read). The sibling nvmet_auth_reply() already validates tl against the structure size; the negotiate path did not. Pass tl into nvmet_auth_negotiate(), reject a tl that does not cover the negotiate data plus one full protocol descriptor, and reject halen/dhlen larger than NVME_AUTH_DHCHAP_MAX_DH_IDS.
