wifi: ath10k: add peer map clean up for peer delete in ath10k_sta_state()
In the Linux kernel, the following vulnerability has been resolved: wifi: ath10k: add peer map clean up for peer delete in ath10k_sta_state() When peer delete failed in a disconnect operation, use-after-free detected by KFENCE in below log. It is because for each vdev_id and address, it has only one struct ath10k_peer, it is allocated in ath10k_peer_map_event(). When connected to an AP, it has more than one HTT_T2H_MSG_TYPE_PEER_MAP reported from firmware, then the array peer_map of struct ath10k will be set muti-elements to the same ath10k_peer in ath10k_peer_map_event(). When peer delete failed in ath10k_sta_state(), the ath10k_peer will be free for the 1st peer id in array peer_map of struct ath10k, and then use-after-free happened for the 2nd peer id because they map to the same ath10k_peer. And clean up all peers in array peer_map for the ath10k_peer, then user-after-free disappeared peer map event log: [ 306.911021] wlan0: authenticate with b0:2a:43:e6:75:0e [ 306.957187] ath10k_pci 0000:01:00.0: mac vdev 0 peer create b0:2a:43:e6:75:0e (new sta) sta 1 / 32 peer 1 / 33 [ 306.957395] ath10k_pci 0000:01:00.0: htt peer map vdev 0 peer b0:2a:43:e6:75:0e id 246 [ 306.957404] ath10k_pci 0000:01:00.0: htt peer map vdev 0 peer b0:2a:43:e6:75:0e id 198 [ 306.986924] ath10k_pci 0000:01:00.0: htt peer map vdev 0 peer b0:2a:43:e6:75:0e id 166 peer unmap event log: [ 435.715691] wlan0: deauthenticating from b0:2a:43:e6:75:0e by local choice (Reason: 3=DEAUTH_LEAVING) [ 435.716802] a
