CVE-2026-80847

CVE-2026-80847 affects the Linux kernel TCP subsystem. The root cause is a divide-by-zero in tcp_select_initial_window(), which assumes the advertised MSS (advmss) is at least 1. Route-derived advmss values can violate this assumption—either via an explicit too-small RTAX_ADVMSS or through the de...
