Overview

CVE-2026-72232 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

batman-adv: ensure minimal ethernet header on TX

As documented in commit 8bd67ebb50c0 ("net: bridge: xmit: make sure we have

at least eth header len bytes"), it is possible by for a local user with

eBPF TC hook access to attach a tc filter which truncates the packet and

redirects to an batadv interface. But the code assumes that at least

ETH_HLEN bytes are available and thus might read outside of the available

buffer.

The batadv_interface_tx() must therefore always check itself if enough data

is available for the ethernet header and don't rely on min_header_len.

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-2026-72232?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-72232 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
