- Summary
- CVE-2025-71227 affecting package kernel 6.6.126.1-1
- Details
-
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 cfg80211getieschannelnumber) 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.
