That is extraordinarily rare and I’m not even sure if it’s possible anymore. That was potential attack vector in the 90’s where you have a port on network switch, and then you flood the cam table with thousands of bogus mac addresses until you fill it up, then the switch turns into a hub, and you can now sniff all traffic traversing the switch. These days I’m not sure what will happen if you do successfully fill up a switches cam table. Also cam table sizes are are much much larger now. ~128k entry’s vs maybe 1000 back in the day.
