CVE-2006-6655

Estado: ModificadaBaja (1.7)—

La implementación de procfs en NetBSD-current anterior al 23/10/2006, NetBSD 3.0 y 3.0.1 anterior al 29/10/2006 permite a usuarios locales provocar una denegación de servicio (error irrecuperable del sistema, "kernel panic") al intentar acceder a /emul/linux/proc/0/stat en un sistema de ficheros procfs que ha sido montado con mount_procfs -o linux, lo cual resulta en una referencia a un puntero NULL.

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).
