Overview

CVE-2024-26779 is a high-severity vulnerability. It was published on April 3, 2024 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: fix race condition on enabling fast-xmit

fast-xmit must only be enabled after the sta has been uploaded to the driver,

otherwise it could end up passing the not-yet-uploaded sta via drv_tx calls

to the driver, leading to potential crashes because of uninitialized drv_priv

data.

Add a missing sta->uploaded check and re-check fast xmit after inserting a sta.

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.
