Description
This vulnerability in the Linux kernel's mac80211 wireless subsystem involves an unnecessary warning triggered when an IBSS (ad-hoc) network has no channel to scan due to regulatory domain changes. The warning occurs because the regulatory domain can change while the IBSS is operating, leaving no allowed channels temporarily during a 60-second grace period before shutdown. The issue has been resolved by removing this warning in such cases.
