Desbordamiento de enteros en la función ping_init_sock en net/ipv4/ping.c en el kernel de Linux hasta 3.14.1 permite a usuarios locales causar una denegación de servicio (uso después de liberación y caída de sistema) o posiblemente ganar privilegios a través de una aplicación manipulada que aprovecha un contador de referencia manejado indebidamente.

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.
