In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Avoid accessing uninitialized arvif->ar during beacon miss During beacon miss handling, ath12k driver iterates over active virtual interfaces (vifs) and attempts to access the radio object (ar) via arvif->deflink->ar. However, after commit aa80f12f3bed ("wifi: ath12k: defer vdev creation for MLO"), arvif is linked to a radio only after vdev creation, typically when a channel is assigned or a scan is requested. For P2P capable devices, a default P2P interface is created by wpa_supplicant along with regular station
