Overview

CVE-2024-26683 is a medium-severity vulnerability affecting linux linux_kernel. It was published on April 2, 2024 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: cfg80211: detect stuck ECSA element in probe resp

We recently added some validation that we don't try to

connect to an AP that is currently in a channel switch

process, since that might want the channel to be quiet

or we might not be able to connect in time to hear the

switching in a beacon. This was in commit c09c4f31998b

("wifi: mac80211: don't connect to an AP while it's in

a CSA process").

However, we promptly got a report that this caused new

connection failures, and it turns out that the AP that

we now cannot connect to is permanently advertising an

extended channel switch announcement, even with quiet.

The AP in question was an Asus RT-AC53, with firmware

3.0.0.4.380_10760-g21a5898.

As a first step, attempt to detect that we're dealing

with such a situation, so mac80211 can use this later.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
