CVE-2026-89554
A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. When reconstructing a Multipath TCP MPTCP join request under SYN cookies, the localid field is not properly initialized. An off-path attacker can influence this uninitialized field by sending concurrent MPJOIN SYN requests...

kernel: TCP-spoofed ghost ACKs and leak leak initial sequence number
A flaw was found in the Linux kernel. Two TCP spoofing primitives exist where an attacker can brute force the server-chosen send window by acknowledging data that was never sent, called "ghost ACKs." There are side channels that also allow the attacker to leak the otherwise secret server-chosen...

What is SYN Spoofing or TCP Reset Attack❓
Syn Spoofing or TCP Reset Attack is a type of attack in which attackers send forged TCP RST Reset packets to the host. This is the most common attack on the Internet which is causing a lot of problems. These attacks are mainly performed to shut down the websites which are not working with them...
Linux: TCP SYN Cookies
Normally, a client sends a SYN to the server which responds and hold state information in the TCP stack. In a SYN flood, the generated SYN packets consume all available TCP memory leading the server to deny service. The TCP SYN cookie is a mechanism to resist such SYN flood attacks. This script...
