Spoofing Attack

kernel is vulnerable to Spoofing Attack. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim’s TCP session or terminate that session, where a Man-in-the-Middle Attack (MITM) performs an IP fragmentation attack and an IPID collision. This flaw allows a remote user to pretend to be the sender of the TCP/IP packet for an existing TCP/IP session.
