How to Fix CVE-2026-72163

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-2026-72163, 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: ocfs2: fix NULL h_transaction deref in ocfs2_assure_trans_credits [BUG] A direct write over unwritten extents can panic the kernel in ocfs2_assure_trans_credits() when the journal aborts during DIO completion. The crash is a general protection fault from a NULL pointer dereference. [CAUSE] ocfs2_dio_end_io_write() loops over a direct write's unwritten extents, marking each written under a single journal handle. If the journal aborts (for example after an I/O error) while the extent tree is being updated, the handle is left aborted with its transaction pointer cleared. The extent merge treats that failure as not critical and reports success, so the loop keeps using the handle. ocfs2_assure_trans_credits() reads the handle's remaining credits without first checking whether the handle is aborted, and that read dereferences the cleared transaction pointer. [FIX] A journal abort is recorded in the handle itself, so callers are expected to test the handle rather than rely on a returned error. Make ocfs2_assure_trans_credits() do that, as the other ocfs2 journal helpers already do, and return -EROFS when the handle is aborted.
