La función assoc_array_gc en la implementación associative-array en lib/assoc_array.c en el kernel de Linux anterior a 3.16.3 no implementa debidamente la recolección de basura, lo que permite a usuarios locales causar una denegación de servicio (referencia a puntero nulo y caída del sistema) o posiblemente tener otro impacto no especificado a través de múltiples operaciones 'keyctl newring' seguidas de una operación 'keyctl timeout'.

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.
