Post Meltdown, Spectre and other Intel issues

This can never be truly called "solved" until it's done in hardware [...]

Perfect example.

While I was doing weekly maintenance on my 32bit Peppermint/Ubu test box, I started thinking ... I've never installed the mitigation tool.

When I was done doing all of the incremental updates, I ran the tool -  mind you, this is with the most recent mainline kernel build - which tests out just fine on my 64bit machines.

Vuln 3 still hasn't been patched:

LoL! I was looking at Conky (above).

259MB RAM being used, sitting idle at the desktop, with CLI open.

Gotta love Peppermint OS ...

Hi VinDSL,
I remember reading that 32 bit systems would patched later. Looking around after your post, I found that 32 bit is still not fully patched, see http://forums.debian.net/viewtopic.php?f=3&t=135775&sid=333beb75703ac577388e4955a1946bf3&start=60#p663711

EDIT: Gentoo keeps an up-to-date list here https://wiki.gentoo.org/wiki/Project:Security/Vulnerabilities/Meltdown_and_Spectre#Resolution

[VinDSL]

Aha! No biggy ...

I only boot this machine every  week or two, and do incremental updates to keep everything up-to-date.

Thx for the heads-up, pin

In my point of view this issue is solved. 4.13.0-36 is fine, not to forget that a firewall, a router and being careful should be more than enough. By the way, anyone using Ukuu? I am not sure if this enhances security?

...and here we go again! Spectre variant 4...

Intels has some sketchy ideas and plans, here is a few:

• Z390 chipset, for WHAT? Just the 8800k?
• At Computex, they "revealed" the 8th gen i9 and overclocked to 5Ghz, but was a Xeon sever CPU witha unlocked multiplier and was cooled by a A/C UNIT.  Yes, you heard me.  And it wasn't the real thing.
