[DISCUSSION] Meltdown and Spectre

I am really curious about how they are going to fix Spectre-related vulnerabilities.

For Spectre bios has to be updated. That falls on motherboard manufacturers.

All motherboards from 2000-2018

Haven’t seen anything for my Gigabyte board.

 

@Mikorist: Your post made me search around for my own MoBo.

I haven't found anything as of yet. (Asus P8Z77-V PRO)

I think you're correct. This issue will probably be pushed off onto the MoBo manufacturers via a BIOS update.

 

If Intel gives a new microcode.

@taviruni Compared to last years release I'm seeing specific updates for Ivy Bridge, Haswell, Broadwell, Skylake, Kaby Lake, Coffee Lake & Gemini Lake CPUs.

Out of the 94 files only 19 of them are different.

I've also seen a Linux update containing one more.

@taviruni To check if it's actually working you should use the powershell script. The result should look the same as the what's within the spoiler.

 

Please read again my previous post just updated.

 

I did, but that result still doesn't mean that you're safe from Spectre. The powershell script will tell you if you are.

 

I tryed but my Powershell on 7x64 can't load the module.

@taviruni You're still vulnerable to Spectre.

If the VMware program did work for you then I guess it didn't update your microcode to a Spectre patched version.

You can download any live-dvd linux distro - boot and test PC to Spectre and Meltdown as well
