I decided today to check what ports are open on my laptop, and found that the only port open to connections from outside is 5353, used by avahi-daemon and by Vivaldi Browser (for the "Anonymize local IPs exposed by WebRTC' feature).
Is there a security risk in having that port open to everyone, especially when using a public WiFi?
