El kernel de Linux desde la 2.2.1 hasta la 2.2.19, y desde la 2.4.1 hasta la 2.4.10, permite a usuarios locales provocar una denegación de servicio mediante una serie de enlaces simbólicos profundamente anidados, lo que hace que el kernel dedique tiempo adicional al intentar acceder al enlace.

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.
