"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: Fix deadlock in ieee80211_sta_ps_deliver_wakeup()\n\nThe ieee80211_sta_ps_deliver_wakeup() function takes sta->ps_lock to\nsynchronizes with ieee80211_tx_h_unicast_ps_buf() which is called from\nsoftirq context. However using only spin_lock() to get sta->ps_lock in\nieee80211_sta_ps_deliver_wakeup() does not prevent softirq to execute\non this same CPU, to run ieee80211_tx_h_unicast_ps_buf() and try to\ntake this same lock ending in deadlock.
