Overview

CVE-2025-38406 is a medium-severity vulnerability. It was published on July 25, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

wifi: ath6kl: remove WARN on bad firmware input

If the firmware gives bad input, that's nothing to do with

the driver's stack at this point etc., so the WARN_ON()

doesn't add any value. Additionally, this is one of the

top syzbot reports now. Just print a message, and as an

added bonus, print the sizes too.

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.
