Descriptions

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.

Se ha detectado un problema en el kernel de Linux versiones hasta 5.16.11. El método de asignación de IPID mixto con la política de asignación de IPID basada en hash permite a un atacante fuera de la ruta inyectar datos en la sesión TCP de una víctima o terminar esa sesión.

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.
