Specter / Meltdown - A atualização do BIOS do Lenovo M800 parece não funcionar

1

Portanto, tenho um Lenovo ThinkCentre M800, executando o Windows 10 x64, 1709. Apliquei a Atualização do BIOS mais recente, que é a versão FWKT86A, e executei o Get-SpeculationControlSettings (no módulo PS do Controle de Especulação que determina se PC ainda está em risco), e ele retorna não protegido. Eu assegurei que o PC está completamente atualizado, e ainda estou mostrando que o PC ainda está vulnerável ao Specter / Meltdown.

Alguém mais se deparou com isso? A atualização do BIOS realmente protege contra o Specter / Meltdown?

Veja os resultados de Get-SpeculationControlSettings:
