CVE-2017-3196

Estado: ModificadaAlta (7.8)—

El framework Rawether de PCAUSA no valida correctamente los datos BPF, permitiendo que un programa BPF malicioso manipulado realice operaciones en la memoria fuera de los límites habituales cuando el controlador recibe los paquetes de red. Los atacantes locales pueden explotar esta vulnerabilidad para ejecutar código arbitrario con privilegios SYSTEM.

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).
