La pila TCP en el kernel de Linux versiones 3.x, no implementa apropiadamente un mecanismo de protección de cookies SYN para el caso de una conexión de red rápida, lo que permite a los atacantes remotos causar una denegación de servicio (consumo de CPU) mediante el envío de muchos paquetes TCP SYN, como es demostrado por un ataque contra el paquete kernel versión 3.10.0 en CentOS Linux versión 7. NOTA: terceros no han podido discernir ninguna relación entre la búsqueda de GitHub Engineering y el código de ataque Trigemini.c.

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
