Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.02%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description

A remote attacker could send connection packets from a spoofed IP address and occupy all server slots, or even use them for a reflection attack using map download packets.
