In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: dont WARN for connections on invalid channels Its not clear (to me) how exactly syzbot managed to hit this, but it seems conceivable that e.g. regulatory changed and has disabled a channel between scanning (channel is checked to be usable by cfg80211_get_ies_channel_number) and connecting on the channel later. With one scenario that isnt covered elsewhere described above, the warning isnt good, replace it with a (more informative) error message.
