CVE-2013-2852

Estado: ModificadaMedia (6.9)—💥 Exploit

Vulnerabilidad de formato de cadena en la función b43_request_firmware de drivers/net/wireless/b43/main.c en el driver del Broadcom B43 inhalambrico para el kernel Linux hasta la versión v3.9.4 permite a usuarios locales conseguir privilegios haciendo uso de acceso root e incluyendo especificaciones de formato de cadena en un parámetro fwpostfix modprobe, provocando una construcción inapropiada de un mensaje de error

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.
