Vulnerabilidad alta en UEFI por falta de verificación de arranque seguro

Una vulnerabilidad en firmware UEFI (CVE-2026-6484, CVSS 8.2) permite la ejecución arbitraria de código debido a la ausencia de verificación criptográfica en ciertos módulos de firmware (FV). Esta falla compromete la cadena de confianza de arranque en servidores, estaciones de trabajo y dispositivos empresariales, siendo particularmente alta en infraestructuras cloud y centros de datos en LATAM donde el firmware no parchado es común.
