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.
