CVE-2017-6074
La función dccp_rcv_state_process en net/dccp/input.c en el kernel de Linux hasta la versión 4.9.11 no maneja adecuadamente estructuras de paquetes de datos DCCP_PKT_REQUEST en el estado LISTEN, lo que permite a usuarios locales obtener privilegios root o provocar una denegación de servicio (liberación doble) a través de una aplicación que hace una llamada de sistema IPV6_RECVPKTINFO setsockopt.
CVSS
- Puntuación base
- 7.8
- Versión
- 3.1
- Vector
- CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días
- 5.96 %
- Percentil entre todas las CVEs puntuadas
- 93
- Fecha de la puntuación
- 20/10/2026
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.
