The vulnerability is due to insufficient policy checks for the logged packets. An attacker could exploit this vulnerability by sending a flood of denied packets that match an access list entry with the log keyword. An exploit could allow the attacker to bypass the access control list for a small percentage of the packets, which would otherwise have been dropped.
