CVE-2013-6282

Estado: AnalizadaAlta (8.8)⚠ Explotación activa💥 Exploit

Las funciones de API (1) get_user y (2) put_user en el kernel de Linux anterior a la versión 3.5.5 en las plataformas v6k y v7 ARM no validan ciertas direcciones, lo que permite a atacantes leer o modificar el contenido de localizaciones de memoria kernel arbitraria a través de una aplicación manipulada, tal y como se explotó activamente en dispositivos Android en Octubre y Noviembre 2013.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 8.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 40%
Percentil entre todas las CVEs puntuadas: 99
Fecha de la puntuación: 10/10/2026

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).

CISA KEV — explotada activamente

Añadida al catálogo: 15/9/2022
Plazo de remediación: 6/10/2022
Uso conocido en ransomware: Unknown

💥 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.
