CVE-2022-43974 describes a critical integer overflow vulnerability in MatrixSSL versions 4.0.4 through 4.5.1, specifically within the matrixSslDecodeTls13 function. This flaw allows a remote, unauthenticated attacker to trigger a buffer overflow via a crafted TLS message, potentially leading to remote code execution. With a CVSS score of 9.8 (Critical), the vulnerability is easily exploitable over the network with no user interaction required, posing a significant risk of complete compromise of confidentiality, integrity, and availability. While no public exploits, Metasploit modules, or Nuclei templates are currently available, and there is minimal community discussion, the high severity warrants immediate patching to version 4.6.0 or later.
