UBUNTU-CVE-2025-38406: Medium severity ubuntu/linux vulnerability

Q: Which Ubuntu systems are in scope?

The affected software list includes Ubuntu linux, linux-aws, linux-azure, linux-gcp, and their corresponding FIPS kernel packages: linux-fips, linux-aws-fips, linux-azure-fips, and linux-gcp-fips.

Q: What condition triggers the issue?

The issue is triggered when the ath6kl Wi-Fi driver receives malformed or otherwise bad firmware input. The resolved change removes a WARN_ON() condition and replaces it with a message that includes the relevant sizes.

Q: What is the reported impact?

The supplied severity vector rates the issue as medium with a 5.1 score and indicates high availability impact, while confidentiality and integrity impacts are listed as none.

Published Jul 25, 2025

Updated

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 WARNON() 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.
