Hi,
unfortunately no.
Intel has not released anything yet, that would to either fix or mitigate either Meltdown and Spectre.
I haven't either seen a full changelog about these, but it is assumed that this updated microcode helps to keep the performance impact on the Meltdown patches in Linux 4.14 somewhat lower.
At the moment we do not have any clear information from the vendors what actually works and what doesn't.
Best, -Michael

Hi, The microcode is the one for fixing (at processor side) the Spectre vulnerability?

Add intel microcode too the distribution and configure dracut in a way that the microcode is loaded early in the boot process.
