How to Fix CVE-2026-89802

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-2026-89802, 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/nouveau/uvmm: fix NULL deref unwinding an OP_MAP_SPARSE op Each bind_job_op is zeroed by kzalloc_obj() in bind_job_op_from_uop(), and the OP_MAP_SPARSE case in nouveau_uvmm_bind_job_submit() only creates a region, so op->ops stays NULL for a successfully processed sparse map. If a later op in the same job fails, the reverse unwind loop revisits that op and calls drm_gpuva_ops_free(&uvmm->base, op->ops) unconditionally. drm_gpuva_ops_free() dereferences its argument right away (list_for_each_entry_safe on &ops->list), so a NULL op->ops oopses. The path is reachable by any render-node fd holder, since NOUVEAU_VM_BIND is DRM_RENDER_ALLOW. Guard the free with IS_ERR_OR_NULL(), as nouveau_uvmm_bind_job_cleanup() already does for the identical free.
