Desbordamiento de búfer en la función smiGetNode en lib/smi.c en libsmi v0.4.8 permite a atacantes dependientes de contexto ejecutar código arbitrario a través de un identificador de objeto (también conocido como OID), representado como una cadena numérica que contiene muchos componentes separados por caracteres . (punto).

CVSS

Puntuación base: 7.5
Versión: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 14 %
Percentil entre todas las CVEs puntuadas: 97
Fecha de la puntuación: 3/11/2026

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.
