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

wifi: mac80211: Update skb's control block key in ieee80211_tx_dequeue()

The ieee80211 skb control block key (set when skb was queued) could have
been removed before ieee80211_tx_dequeue() call. ieee80211_tx_dequeue()
already called ieee80211_tx_h_select_key() to get the current key, but
the latter do not update the key in skb control block in case it is
NULL. Because some drivers actually use this key in their TX callbacks
(e.g. ath1{1,2}k_mac_op_tx()) this could lead to the use after free
below:

Reset SKB control block key before calling ieee80211_tx_h_select_key()
to avoid that.
