CVE-2022-38100
A threat actor with network access can remotely issue a specially formatted UDP request that will cause the entire device to crash and require a physical reboot.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.97%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description

A threat actor with network access can remotely issue a specially formatted UDP request that will cause the entire device to crash and require a physical reboot. A UDP broadcast request could be sent that causes a mass denial-of-service attack on all CME8000 devices connected to the same network.
