La implementación de ciertas operaciones de archivo splice_write en el kernel de Linux anterior a 3.16 no fuerza una restricción en el tamaño máximo de un archivo, lo que permite a usaurios locales causar una denegación de servicio (caída del sistema) o la posibilidad de tener otro impacto no especificado a través de llamadas anidadas al sistema modificadas, como se ha demostrado mediante el uso de un archivo descriptor asociado con sistemas de ficheros ext4.

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.
