CVE-2014-7975
Estado: ModificadaMedia (5.5)—
La función do_umount en fs/namespace.c en el kernel de Linux hasta 3.17 no requiere la capacidad CAP_SYS_ADMIN para llamadas do_remount_sb que cambian el sistema de ficheros root a sólo lectura, lo que permite a usuarios locales causar una denegación de servicio (pérdida de la habilidad de escritura) mediante la realización de ciertas llamadas a la liberación de sistemas, la limpieza del indicador / MNT_LOCKED, y la realización de una llamada al sistema umount MNT_FORCE.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- Puntuación base: 5.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.46%
- Percentil entre todas las CVEs puntuadas: 38
- Fecha de la puntuación: 13/10/2026
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).
