Does this matter?

Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.

Description

On affected platforms running Arista EOS with MACsec configuration, a specially crafted packet can cause the MACsec process to terminate unexpectedly. Continuous receipt of these packets with certain MACsec configurations can cause longer term disruption of dataplane traffic.
