"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath12k: clear stale link mapping of ahvif->links_map\n\nWhen an arvif is initialized in non-AP STA mode but MLO connection\npreparation fails before the arvif is created\n(arvif->is_created remains false), the error path attempts to delete all\nlinks. However, link deletion only executes when arvif->is_created is true.\nAs a result, ahvif retains a stale entry of arvif that is initialized but\nnot created.\n\nWhen a new arvif is initialized with the same link id, this stale mapping\ntriggers the following WARN_ON.\n\nWARNING: drivers/net/wireless/ath/ath12k/mac.c:4271 at ath12k_mac_op_change_vif_links+0x140/0x180 [ath12k], CPU#3: wpa_supplicant/275\n\nCall trace:\n ath12k_mac_op_change_vif_links+0x140/0x180 [ath12k] (P)\n drv_change_vif_links+0xbc/0x1a4 [mac80211]\n ieee80211_vif_update_links+0x54c/0x6a0 [mac80211]\n ieee80211_vif_set_links+0x40/0x70 [mac80211]\n ieee80211_prep_connection+0x84/0x450 [mac80211]\n ieee80211_mgd_auth+0x200/0x480 [mac80211]\n ieee80211_auth+0x14/0x20 [mac80211]\n cfg80211_mlme_auth+0x90/0xf0 [cfg80211]\n nl80211_authenticate+0x32c/0x380 [cfg80211]\n genl_family_rcv_msg_doit+0xc8/0x134\n\nFix this issue by unassigning the link vif and clearing ahvif->links_map\nif arvif is only initialized but not created.\n\nTested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.5-01651-QCAHKSWPL_SILICONZ-1"
