UBUNTU-CVE-2024-40941: Medium severity ubuntu/linux-azure vulnerability

Q: Which systems are exposed to this issue?

The affected software list includes Ubuntu linux, linux-fips, linux-azure, linux-aws-fips, linux-azure-fips, linux-gcp-fips, linux-gcp, and linux-oracle packages. Exposure specifically involves systems using the iwlwifi MVM Wi-Fi driver and receiving malformed firmware notifications.

Q: What does exploitation require?

The issue is triggered when firmware sends a notification that claims to contain more data than was allocated for that notification. The provided vector indicates adjacent-network attack access, low attack complexity, no privileges, and no user interaction.

Q: What is the impact of a successful trigger?

The kernel may read past the allocated notification buffer. The supplied impact vector identifies availability impact as high, with no stated impact to confidentiality or integrity.

Q: Is there a mitigation if an update cannot be applied immediately?

The fix removes printing of the notification buffer; notification content can instead be inspected using tracing if needed. The provided data does not describe a configuration-based workaround or temporary mitigation for unpatched systems.

Published Jul 12, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: don't read past the mfuart notifcation In case the firmware sends a notification that claims it has more data than it has, we will read past that was allocated for the notification. Remove the print of the buffer, we won't see it by default. If needed, we can see the content with tracing. This was reported by KFENCE.

Frequently Asked Questions

Which systems are exposed to this issue?

The affected software list includes Ubuntu linux, linux-fips, linux-azure, linux-aws-fips, linux-azure-fips, linux-gcp-fips, linux-gcp, and linux-oracle packages. Exposure specifically involves systems using the iwlwifi MVM Wi-Fi driver and receiving malformed firmware notifications.

What does exploitation require?

The issue is triggered when firmware sends a notification that claims to contain more data than was allocated for that notification. The provided vector indicates adjacent-network attack access, low attack complexity, no privileges, and no user interaction.

What is the impact of a successful trigger?

The kernel may read past the allocated notification buffer. The supplied impact vector identifies availability impact as high, with no stated impact to confidentiality or integrity.

Is there a mitigation if an update cannot be applied immediately?

The fix removes printing of the notification buffer; notification content can instead be inspected using tracing if needed. The provided data does not describe a configuration-based workaround or temporary mitigation for unpatched systems.
