Unassigned; IANA registers nothing between 14414 and 14500, and 14441 sits in that hole.
IANA leaves 14441 unassigned — the surrounding registrations are ca-web-update (14414, CA eTrust Web Update Service) and xpra (14500, the xpra network protocol). Nmap's service table lists it as unknown. No published product default, malware family, or scanner signature is tied to it. Note that 14441 and 14442 are frequently seen together, which usually means one application claimed a small consecutive block for a control and a data channel rather than that either number is registered.
Expose with care
Unknown listener. If it appears alongside 14442, identify both — a paired control/data channel is often an internal-only protocol.
