CVE-2020-5388

Estado: ModificadaMedia (6.9)—

Dell Inspiron 15 7579 2-en-1 BIOS versiones anteriores a 1.31.0, contienen una vulnerabilidad de verificación de búfer de comunicación SMM Inapropiada. Un usuario malicioso autenticado local podría potencialmente explotar esta vulnerabilidad mediante el uso de una SMI para obtener una ejecución de código arbitraria en SMRAM

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).
