How to Fix CVE-2026-72329

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-2026-72329, 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: net/liquidio: drop cached VF pci_dev LUT The PF SR-IOV enable path caches VF pci_dev pointers in dpiring_to_vfpcidev_lut[] by iterating with pci_get_device(). Those entries do not own a reference, because the iterator drops the previous device reference on each step. The cached pointer is then dereferenced later when handling OCTEON_VF_FLR_REQUEST. Replace the cached VF mapping with runtime lookup on the mailbox DPI ring: derive the VF index from q_no, resolve the VF via exported PCI IOV helpers, validate it with the PF pointer and VF ID, then issue pcie_flr() and drop the reference with pci_dev_put(). Remove the unused VF lookup table initialization and cleanup.
