Yes, you should still apply firmware updates if they are available for your systems. The mitigations help to protect systems that have the vulnerability, but they do not address the underlying vulnerability. To resolve this vulnerability issue, we urge people and companies using business PCs and devices that incorporate Intel AMT, Intel ISM or Intel SBT to apply any available firmware updates from your equipment manufacturer as soon as possible. Please check with your computer manufacturer for availability of firmware updates for your specific systems and other details.
