"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath11k: cleanup arsta in ath11k_mac_peer_cleanup_all()\n\nWhen mac80211 removes a sta, it calls .sta_state() which in turn calls\nath11k_mac_station_remove(). In that function we clean up both peers &\narsta related resources.\n\nBut when the firmware crashes, ath11k calls ieee80211_restart_hw(), which\nassumes that all driver related resources are cleaned up beforehand. This\ncleanup is supposedly done by ath11k_mac_peer_cleanup_all() but does not\nin fact free arsta->rx_stats / tx_stats.\n\nExtract the arsta cleanup from ath11k_mac_station_remove() into a\nnew ath11k_mac_station_cleanup() and call it from both there and\nath11k_mac_peer_cleanup_all().\n\nThis should handle kmemleaks reports like:\n\tunreferenced object 0xffffff801ae66400 (size 1024):\n\t comm \"hostapd\", pid 1306, jiffies 4295011565\n\t hex dump (first 32 bytes):\n\t 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................\n\t 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................\n\t backtrace (crc d61c08ec):\n\t kmemleak_alloc+0x3c/0x50\n\t __kmalloc_cache_noprof+0x2b0/0x3e0\n\t ath11k_mac_op_sta_state+0x1dc/0xb10\n\t drv_sta_state+0xac/0x6f8\n\t sta_info_insert_rcu+0x314/0x5e0\n\t sta_info_insert+0x14/0x38\n\t ieee80211_add_station+0x10c/0x1a0\n\t nl80211_new_station+0x3e8/0x680\n\t genl_family_rcv_msg_doit+0xc0/0x120\n\t genl_rcv_msg+0x1b4/0x258\n\t netlink_rcv_skb+0x4c/0x108\n\t genl_rcv+0x38/0x60\n\t netlink_unicast+0x190/0x278\n\t netlink_sendmsg+0x15c/0x370\n\t ____sys_sendmsg+0x120/0x290\n\t ___sys_sendmsg+0x70/0xa0\n\nTested-on: QCN9074 hw1.0 PCI WLAN.HK.2.9.0.1-01977-QCAHKSWPL_SILICONZ-1"
