Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: mac80211: validate individual TWT params before driver setup<br /> <br /> ieee80211_process_rx_twt_action() only partially validates a received<br /> S1G TWT setup frame before queueing it.<br /> <br /> An individual agreement can therefore reach ieee80211_s1g_rx_twt_setup()<br /> with twt-&gt;length too short for the full struct ieee80211_twt_params.<br /> <br /> The individual path passes twt to drv_add_twt_setup(). Both the tracepoint<br /> and the driver callback consume the complete parameters block, not merely<br /> req_type. Do not pass a short individual agreement to the driver.<br /> Broadcast agreements remain unchanged because they are rejected locally<br /> after accessing only req_type.<br /> <br /> [edit commit message to not overclaim lack of validation nor<br /> understate driver impact]
