• CVE-2026-56123HIGH 8.1

  socat, a utility for establishing two-way network data streams, has a critical flaw in how it parses SOCKS5 proxy responses. When connecting through a malicious SOCKS5 proxy, an attacker can craft a specially formed response that causes socat to write arbitrary data into its own memory beyond the intended boundaries. This memory corruption could allow the attacker to crash the application or potentially execute code on the affected system. The vulnerability affects socat versions 1.8.0.0 through 1.8.1.1.
