'Kernel memory leaking' Intel processor design flaw forces Linux, Windows redesign

Because of a design flaw in Intel processors chips expect slowdowns after Windows and Linux updates.

Quote

Programmers are scrambling to overhaul the open-source Linux kernel's virtual memory system. Meanwhile, Microsoft is expected to publicly introduce the necessary changes to its Windows operating system in an upcoming Patch Tuesday

Quote

Crucially, these updates to both Linux and Windows will incur a performance hit on Intel products. The effects are still being benchmarked, however we're looking at a ballpark figure of five to 30 per cent slow down

most likely a common tax practice here in the states called a Non-Qualified Stock Option.

It'll be interesting to see what happens to cloud providers who almost universally run on Intel Xeons as a result of this. The security implications from what I understand are pretty extreme.

This is turning out to be much worse and bigger that we thought.

I read some info about antivirus software interfering with the update.  It says here

https://forum.avast.com/index.php?topic=212648.msg1439270#msg1439270

that an update for Avast was issued a couple of days ago for Avast version 8 or later.  But some users are still reporting problems. 

The CCleaner SLIM version is always released a bit after any new version; when it is it will be HERE :-)

Pssssst: ... It isn't really a cloud. Its a bunch of big, giant servers.

Here is the latest as regards to where your av provider is with this

https://docs.google.com/spreadsheets/d/184wcDt9I9TUNFFbsAVLpzAtckQxYiuirADzf3cL42FQ/htmlview?sle=true#gid=0

I use Emsisoft which,  through its updater, set the required reg key needed for the Windows update  KB40506892  All went ok although Windows was waiting for a restart afterwards. (win 10 build 1709)

All Apple products are affected by the Meltdown and Spectre chip vulnerabilities as well as most Windows machines.

Some problems created for Sandboxie are apparently fixed by beta version 5.23.3.  Read the first post and those on page 3. 

https://forums.sandboxie.com/phpBB3/viewtopic.php?f=64&t=25114

I think that means no help for win xp users who can only use up to ver 5.22.  Is that right?

I think it only affect Win 7 users.

I am still on 5.22 on Win 10 after the Microsoft Update and have no issues.

I did update Win 7 to 5.23.3 and have no problem after the win Update.

The initial reporting of this was all over the place. The headlines all said intel only when in reality it was pretty much every modern pc. There were also reports saying a 30% hit to performance when that isn't on desktop use but only linux servers. Everything thing I've seen about desktop use has shown benchmarks that are pretty much negligible in performance difference. Now that could change as the patches are updated but I haven't noticed any difference on my computers yet.

Really easy to read article about what happened and why everyone, apart from users, knew about it for seven months before it exploded on the internet info chain.
