A flaw was found in Dnsmasq. The default maximum EDNS.0 UDP packet size was set to 4096 but should be 1232 because of DNS Flag Day 2020.
Mitigation
Systems that can not be updated can still configure dnsmasq to use the recommended maximum EDNS value by setting edns-packet-max=1232 in the dnsmasq configuration.
