Overview

CVE-2026-80722 is a high-severity vulnerability. It was published on August 28, 2026 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: validate individual TWT params before driver setup

ieee80211_process_rx_twt_action() only partially validates a received

S1G TWT setup frame before queueing it.

An individual agreement can therefore reach ieee80211_s1g_rx_twt_setup()

with twt->length too short for the full struct ieee80211_twt_params.

The individual path passes twt to drv_add_twt_setup(). Both the tracepoint

and the driver callback consume the complete parameters block, not merely

req_type. Do not pass a short individual agreement to the driver.

Broadcast agreements remain unchanged because they are rejected locally

after accessing only req_type.

[edit commit message to not overclaim lack of validation nor

understate driver impact]

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.
