How to Fix CVE-2026-98778

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-2026-98778, 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In the Linux kernel, the following vulnerability has been resolved: binder: fix is_failure flag for superseded transaction cleanup When a TF_UPDATE_TXN transaction supersedes a pending async transaction, binder_release_entire_buffer() is called with is_failure=false. Since the superseded transaction was never delivered, binder_apply_fd_fixups() was never called and no fds were installed in the target process. With is_failure=false, the BINDER_TYPE_FDA cleanup handler interprets stale buffer contents as installed fd numbers and passes them to binder_deferred_fd_close(), closing unrelated file descriptors. Pass is_failure=true since the transaction was never delivered to the target, matching the semantics of all other undelivered-transaction cleanup paths.
