Cisco Application Policy Infrastructure Controller Denial of Service Vulnerability

A vulnerability in the Cisco Nexus 9000 Series Platform Leaf Switches for Application Centric Infrastructure (ACI) could allow
an unauthenticated, adjacent attacker to cause a denial of service (DoS)
condition on the affected device.

The vulnerability is due to
improper handling of a type of Layer 2 control plane traffic. An attacker could exploit
this vulnerability by sending crafted traffic to a host behind a leaf switch. An
exploit could allow the attacker to cause a DoS condition on the affected device.

Cisco has released software updates that address this vulnerability. There are no workarounds that mitigate this vulnerability.
