I can offer two reasons why it might be so. The first is that there's a
bug in dnsmasq, which is not unheard-of, but this is old code and a bug
has not been observed before. The second is that you're running dnsmasq
configured to always send broadcasts, using the --dhcp-broadcast option.

Check all the dnsmasq configuration files, that's the sort of thing that
gets slipped in because is solves someone's problem one time, and "it
can't do any harm".
