How to Fix CVE-2026-89807

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-2026-89807, 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: drm/amdkfd: guard against NULL restore_mqd in CRIU queue restore Both create_queue_cpsch() and create_queue_nocpsch() unconditionally call mqd_mgr->restore_mqd() when a CRIU restore is in progress (qd != NULL), with no NULL guard. On any system where restore_mqd is not implemented for the given queue type, a user holding CAP_CHECKPOINT_RESTORE can trigger a kernel NULL pointer dereference and panic the machine by issuing KFD_IOC_CRIU_OP_RESTORE with a crafted queue restore object. Note that checkpoint_mqd is likewise unimplemented on GFX12, so no legitimate CRIU image can reach this path — only a hand-crafted restore payload. Add a NULL guard for restore_mqd immediately after mqd_mgr is resolved, unwinding via the existing error labels and returning -EOPNOTSUPP if the callback is not implemented. This mirrors the existing checkpoint_mqd guard in checkpoint_mqd().
