So it looks like there are two different issues here:

This is a known bug in dnsmasq and has been fixed upstream (according to the thread quoted below). Apparently it is IPv6 related and triggered by Windows and Mac clients. An extensive thread on the subject is here on the OpenWRT forum: https://forum.openwrt.org/t/security-advisory-2021-01-19-1-dnsmasq- multiple-vulnerabilities/85903/123 I think this has been reported in the fallout of the quoted security vulnerabilities.
