  "details": "In the Linux kernel, the following vulnerability has been resolved:  wifi: mac80211_hwsim: avoid NULL skb in stop queue drain  mac80211_hwsim_stop() drops any frames left in data-\u003epending. The loop currently checks skb_queue_empty() and then dequeues separately.  That split is racy with TX status handling, which can remove a pending frame under the queue lock. If the last entry is removed after the empty check, skb_dequeue() returns NULL and the stop path passes that NULL skb to ieee80211_free_txskb().  Use skb_dequeue() as the loop condition instead. The dequeue result is the object that stop owns and frees, and a concurrent status completion that empties the queue simply makes the loop terminate.",
