Description The IPv6 snooping functionality in the first-hop security subsystem does not properly implement the Control Plane Protection feature, allowing remote attackers to cause a denial of service via a flood of ND packets. This issue exists due to insufficient input validation, which can be exploited by an unauthenticated, remote attacker to cause an affected device to reload.
