CVE-2013-2094

Estado: AnalizadaAlta (8.4)⚠ Explotación activa💥 Exploit

La función perf_swevent_init en kernel/events/core.c en el Kernel de Linux anterior a v3.8.9 usa un tipo de datos entero incorrecto, lo que permite a usuarios locales ganar privilegios mediante una llamada al sistema perf_event_open especialmente diseñada.

CVSS

Probabilidad de explotación (EPSS)

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

💥 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.

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad en kernel Linux explorada localmente sin privilegios (AV:L/PR:N) para escalar privilegios mediante perf_event_open, confirmada en KEV con uso activo en ransomware. Permite ejecución con permisos elevados.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
