Description

CVE-2025-71227 affecting package kernel 6.6.126.1-1

In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: don't WARN for connections on invalid channels

It's 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 isn't covered elsewhere described above,

the warning isn't good, replace it with a (more informative)

error message.
