How to install/update Intel microcode firmware on Linux

Correct. I didn’t see any updated message.

Thanks Bayyu P.

Good explanation. Thanks Vivek.

I’m getting an error message.
sudo update-initramfs -u

Thank you

Hi NixCraft, Vivek,

Do you have any update about this Meltdown and spectre vulnerability and new release of intel microcode firmware on linux hosts?
