kernel is vulnerable to man-in-the-middle (MitM). The vulnerability exists through the way IPv4 and IPv6 protocol sequence numbers and fragment IDs were generated could allow a man-in-the-middle attacker to inject packets and possibly hijack connections. Protocol sequence numbers and fragment IDs are now more random.
