CVE-2026-68331

Published Aug 10, 2026 EPSS 0.17% (7th pctl)

Overview

CVE-2026-68331 is a known-severity vulnerability. It was published on August 10, 2026.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

dpaa2-eth: put MAC endpoint device on disconnect

fsl_mc_get_endpoint() returns the MAC endpoint device with a reference

taken through device_find_child(). The Ethernet connect path stores that

device in mac->mc_dev and keeps it for the lifetime of the connected MAC

object.

However, the disconnect path only disconnects and closes the MAC before

freeing the dpaa2_mac object. It does not drop the endpoint device

reference stored in mac->mc_dev, so every successful connect leaks that

device reference when the MAC is later disconnected.

Drop the endpoint device reference after closing the MAC and before

freeing the dpaa2_mac object.

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.
