CVE-2022-43501 affects Zuken Elmic KASAGO TCP/IP stack products, including kasago_ipv4 and kasago_ipv6/v4_dual, due to insufficient randomness in Initial Sequence Number (ISN) generation. This critical vulnerability (CVSS 9.1) allows an unauthenticated attacker to remotely hijack existing TCP connections or spoof future ones, leading to high impact on confidentiality and integrity. While no public exploits or active exploitation have been observed, and community discussion is minimal, the inherent ease of exploitation (low attack complexity) warrants attention.
