The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input when an IPv6 self IP address is configured and the ipv6.strictcompliance database key is enabled (disabled by default) on a BIG-IP system. A remote attacker can send specially crafted IPv6 traffic to the system and perform a denial of service (DoS) attack.
