CVE-2026-74464

Published Aug 15, 2026 EPSS 0.18% (7th pctl)

Overview

CVE-2026-74464 is a known-severity vulnerability. It was published on August 15, 2026.

Technical Description

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

net: openvswitch: fix skb leak on flow key update failure during ct

ovs_ct_execute() always steals or frees the skb on failure while

ovs_flow_key_update() does not. So, if it fails and we return right

away, the skb ends up leaked.

Fix that by breaking instead and letting the common error handling

code at the bottom of the loop to free the skb properly.

This is a very unlikely scenario as it requires the packet to become

unparseable by applying a set of actions on a previously parseable skb,

but should be fixed nevertheless.

Reported by Sashiko.

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.
