A vulnerability in the IP Version 6 (IPv6) packet processing functions of Cisco IOS XR Software,
Cisco IOS XE Software, and Cisco NX-OS Software could allow an unauthenticated, remote attacker to
cause an affected device to stop processing IPv6 traffic, leading to a denial of service (DoS)
condition on the device.
The vulnerability is due to insufficient processing logic for crafted IPv6 packets that are sent
to an affected device. An attacker could exploit this vulnerability by sending crafted IPv6
Neighbor Discovery packets to an affected device for processing. A successful exploit could allow
the attacker to cause the device to stop processing IPv6 traffic, leading to a DoS condition on
the device.
Cisco will release software updates that address this vulnerability. There are no workarounds that
address this vulnerability.
