Summary

The Linux kernel wifi cfg80211 subsystem from 6.11 calls rdev_get_radio_mask in cfg80211_calculate_bi_data with a wireless device's netdev even when that netdev can be NULL. This NULL netdev then crashes mac80211.

Description from the CNA

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: don't get the radio mask for netdev-less wdevs cfg80211_calculate_bi_data() calls rdev_get_radio_mask() with wdev->netdev, which can be NULL and then crashes in mac80211. To avoid that, invert the order of checks since wdev->netdev is always valid for beaconing interfaces.
