My guess is: UDP sockets for outgoing query
from Unbound to authoritative servers.
I also see these "listening" UDP sockets at my laptop running unbound
when resolver is under load. And I see no them when no load.
That was my first thought too, but these entries do not have a
destination IP or port, so it "appears" that these sockets are
listening. Still it could be that perhaps these are sockets
that are starting up for use or something?

from time to time "netstat -l" shows unbound listening on some
high-ports not
bound to 127.0.0.1 - that makes no sense when the service is
configured for
127.0.0.1 only as a local resolver on a inbound mailfilter
