Una condición de carrera en la implementación de fsnotify en el kernel de Linux hasta la versión 4.12.4, permite a los usuarios locales alcanzar privilegios o causar una denegación de servicio (corrupción de memoria) por medio de una aplicación creada que aprovecha la ejecución simultánea de las funciones inotify_handle_event y vfs_rename.

CVSS

Puntuación base: 7
Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 1.22 %
Percentil entre todas las CVEs puntuadas: 68
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.
