CVE-2014-0038
Estado: ModificadaMedia (6.9)—💥 Exploit
La función compat_sys_recvmmsg en net/compat.c en el kernel de Linux anterior a 3.13.2 cuando está habilitado CONFIG_X86_X32, permite a usuarios locales ganar privilegios a través de una llamada al sistema recvmmsg manipulada con un parámetro puntero a "timeout" manipulado.
CVSS
- Versión: 2.0
- Vector: AV:L/AC:M/Au:N/C:C/I:C/A:C
- Puntuación base: 6.9
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 35%
- Percentil entre todas las CVEs puntuadas: 98
- Fecha de la puntuación: 11/10/2026
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.
