Integrity High (I:H)
Availability High (A:H)

How to Fix CVE-2026-93095

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-2026-93095, 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: hfsplus: validate thread record before delete key rebuild hfsplus_delete_cat() is called with str == NULL when the last open reference to an unlinked HFS+ hardlink backing inode is closed. In that case, the function finds the catalog thread by CNID and rebuilds the catalog key from thread.nodeName. That reconstruction path reads thread.nodeName.length directly from the catalog B-tree into fd.search_key and then copies length * 2 bytes into fd.search_key->cat.name.unicode. It does not first check that the found record is a thread record or that its size matches the thread name. A corrupted image can therefore provide an oversized thread name length and make hfs_bnode_read() write past the catalog search-key allocation. Read the CNID record through hfsplus_brec_read_cat(), which bounds the record read to sizeof(hfsplus_cat_entry) and verifies that a thread record's size exactly matches nodeName.length. Together, these checks ensure an accepted thread name fits HFSPLUS_MAX_STRLEN. Reject non-thread records before building the delete key from the validated thread name. Share the thread-record-type helper between hfsplus_find_cat() and hfsplus_delete_cat().
