  "details" : [ "An issue was discovered in the Linux kernel through 5.16.11. 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.", "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." ],
