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] (NVD)
