CVE-2022-1516 [MEDIUM] Linux kernel (AWS) vulnerabilities
Title: Linux kernel (AWS) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Xuewei Feng, Chuanpu Fu, Qi Li, Kun Sun, and Ke Xu discovered that the TCP
implementation in the Linux kernel did not properly handle IPID assignment.
A remote attacker could use this to cause a denial of service (connection
termination) or inject forged data. (CVE-2020-36516)
Ke Sun, Alyssa Milburn, Henrique Kawakami, Emma Benoit, Igor Chervatyuk,
Lisa Aichele, and Thais Moreira Hamasaki discovered that the Spectre
Variant 2 mitigations for AMD processors on Linux were insufficient in some
situations. A local attacker could possibly use this to expose sensitive
information. (CVE-2021-26401)

CVE-2020-36516 [MEDIUM] CWE-290 kernel: off-path attacker may inject data or terminate victim's TCP session
kernel: off-path attacker may inject data or terminate victim's TCP session
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.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, appl

## Abstract
Nowadays traffic on the Internet has been widely encrypted to protect its confidentiality and privacy. However, traffic encryption is always abused by attackers to conceal their malicious behaviors. Since the encrypted malicious traffic has similar features to benign flo
