Description
A vulnerability in Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a device to reload.

An attacker could exploit this vulnerability by sending the Ethernet frames onto the Ethernet segment. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition.
