How to Fix CVE-2026-89453

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-2026-89453, 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: iommu/amd: Put PCI device after handling PPR faults iommu_call_iopf_notifier() looks up the requester with pci_get_domain_bus_and_slot(), which returns a PCI device with its reference count incremented. Neither the successful iommu_report_device_fault() path nor the abort path drops that reference, so every handled PPR request leaks a PCI device reference. This is the same ownership rule that was fixed for the old iommu_v2 ppr_notifier() path by commit 6cf0981c2233 ("iommu/amd: Fix pci device refcount leak in ppr_notifier()"), but iommu_call_iopf_notifier() was added later as a separate PPR/IOPF notifier path. Drop the PCI device reference after handling the PPR entry.
