  "description": "In the Linux kernel, the following vulnerability has been resolved:  wifi: ath12k: clear stale link mapping of ahvif-\u003Elinks_map  When an arvif is initialized in non-AP STA mode but MLO connection preparation fails before the arvif is created (arvif-\u003Eis_created remains false), the error path attempts to delete all links. However, link deletion only executes when arvif-\u003Eis_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.
