Overview

CVE-2024-26682 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: mac80211: improve CSA/ECSA connection refusal

As mentioned in the previous commit, we pretty quickly found

that some APs have ECSA elements stuck in their probe response,

so using that to not attempt to connect while CSA is happening

we never connect to such an AP.

Improve this situation by checking more carefully and ignoring

the ECSA if cfg80211 has previously detected the ECSA element

being stuck in the probe response.

Additionally, allow connecting to an AP that's switching to a

channel it's already using, unless it's using quiet mode. In

this case, we may just have to adjust bandwidth later. If it's

actually switching channels, it's better not to try to connect

in the middle of that.

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.
