Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect processing of active TCP sessions. A remote attacker can send a large number of requests that trigger a TCP connection to move to the LAST_ACK state when there is more data to send and consume all available mbufs, resulting in a denial of service condition.
