In the Linux kernel, the following vulnerability has been resolved:

wifi: ath12k: clear stale link mapping of ahvif->links_map

When an arvif is initialized in non-AP STA mode but MLO connection preparation fails before the arvif is created (arvif->is_created remains false), the error path attempts to delete all links. However, link deletion only executes when arvif->is_created is true. As a result, ahvif retains a stale entry of arvif that is initialized but not created.

When a new arvif is initialized with the same link id, this stale mapping triggers the following WARN_ON.

WARNING: drivers/net/wireless/ath/ath12k/mac.c:4271 at ath12k_mac_op_change_vif_links+0x140/0x180 [ath12k], CPU#3: wpa_supplicant/275

Fix this issue by unassigning the link vif and clearing ahvif->links_map if arvif is only initialized but not created.
