Overview

CVE-2026-72230 is a known-severity vulnerability. It was published on August 15, 2026.

Technical description

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

batman-adv: frag: free unfragmentable packet

The caller of batadv_frag_send_packet() assume that the skb provided to the

function are always consumed. But the pre-check for an empty payload or the

zero fragment size returned an error without any further actions.

A failed pre-check must use the same error handling code as the rest of the

function.

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.

How can CyberStrike help with CVE-2026-72230?

CyberStrike is an open-source, AI-augmented pentesting engine.
