What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

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

wifi: mac80211: don't warn when an IBSS has no channel to scan

ieee80211_request_ibss_scan() warns when regulatory leaves no allowed channel, but that can happen as the regdomain can change while IBSS is operating, and it can continue to operate briefly during the 60s grace period until it's shut down.

Just remove the warning in this case.
