La implementación de VT (vt_ioctl.c) en el núcleo de Linux 2.6.12, y posiblemente en otras versiones, incluida la 2.6.14.4, permite a usuarios locales utilizar el ioctl KDSKBSENT sobre terminales de otros usuarios y obtener privilegios, como se demostró modificando las asignaciones de teclas mediante loadkeys.

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.
