Overview

CVE-2026-72329 is a critical-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 9.3 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.3, rated CRITICAL. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
