CVE-2026-80722

High

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]
