CVE-2006-3824

Estado: ModificadaMedia (4.9)—💥 Exploit

systeminfo.c para Sun Solaris permite a usuarios locales leer memoria del núcleo mediante un valor 0 para el argumento de número de variables en la llamada al sistema sysinfo, lo cual provoca que se utilice un argumento -1 en la función copyout. NOTA: este problema ha sido referido como un desbordamiento superior de entero, pero probablemente se parece más a un error de presencia de signo o un desbordamiento inferior de entero.

CVSS

Probabilidad de explotación (EPSS)

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.
