La función xfrm_replay_verify_len en net/xfrm/xfrm_user.c en el kernel de Linux hasta la versión 4.10.6 no valida ciertos datos de tamaño después de una actualización XFRM_MSG_NEWAE, lo que permite a usuarios locales obtener privilegios de root o provocar una denegación de servicio (acceso fuera de límites basado en memoria dinámica) aprovechando la capacidad CAP_NET_ADMIN, como se demostró durante una competición Pwn2Own en CanSecWest 2017 para el paquete Ubuntu 16.10 linux-image-* 4.8.0.41.52.

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.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
