How to Fix CVE-2026-89800

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-2026-89800, 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: clear the dirty flag when unwinding an OP_UNMAP_SPARSE A successful OP_UNMAP_SPARSE marks its region dirty with nouveau_uvma_region_dirty() and defers the teardown to nouveau_uvmm_bind_job_cleanup(); it does not remove the region from uvmm->region_mt. If a later op in the job fails, the unwind path never clears reg->dirty (set in one place, cleared nowhere) and sets op->reg = NULL, so cleanup skips the teardown. The region is left in the tree with dirty set and its completion never signalled. Later binds over that range then fail permanently -- -ENOENT or -EINVAL from the dirty checks, or an unkillable wait_for_completion() in bind_validate_region() -- for the lifetime of the uvmm. Clear reg->dirty when the unwind reverts the sparse unmap, restoring the region to the state it was found in.
