CVE-2017-3804
A vulnerability in Intermediate System-to-Intermediate System (IS-IS) protocol packet processing of Cisco Nexus 5000, 6000, and 7000 Series Switches software could allow an unauthenticated, adjacent attacker to cause a reload of the affected device.
Does this matter?
Lower severity and a low EPSS score (0.63%). Track it; it rarely justifies an emergency change on its own.
