Doc Text:
A TCP/IP packet spoofing attack flaw was found in the Linux kernel’s TCP/IP protocol, 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.

Description Marian Rehak 2022-03-02 10:53:52 UTC 
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.
