Description

A flaw was found in the Linux kernel's `ath12k` Wi-Fi driver. When an `arvif` (Access Point Virtual Interface) is initialized in non-AP STA mode and a Multi-Link Operation (MLO) connection fails before the `arvif` is fully created, a stale link mapping can persist. This can lead to a kernel warning (`WARN_ON`) when a new `arvif` is initialized with the same link ID, potentially causing system instability or unexpected behavior.
