El uso posterior del mismo conjunto de valores de PCR en Eventlog.Verify carece de la autenticaci\u00f3n llevada a cabo por la verificaci\u00f3n de citas, lo que significa que un atacante local podr\u00eda acoplar esta vulnerabilidad con un registro TCG dise\u00f1ado de forma maliciosa en Eventlog.Verify para falsificar eventos en el registro TCG, derrotando as\u00ed el arranque medido comprobado de forma remota.
