News articles such as this one make it seem like a rare thing.

Bugs that let you access ring 0 data from ring 3 are.

my advice is to not update any patch with regards this flaw until such time it has been deemed safe to do so otherwise your system could become very sluggish or fail to boot

Thanks, but with all due respect- on this sort of material there are sources who I'd rather trust than Auntie Beeb

But it should make the vulnerability more widely known, which overall is probably a good thing (although Intel might differ!) as it will scare more people into installing the latest updates.

If El Reg is to be believed, Apple have already incorporated it into macOS 10.13.2, which was released some weeks ago and which I'm running. It does seem a bit slower in some areas, that may also be due to a new video subsystem, but nothing noticeable (in normal use) otherwise.

I haven't tried really hammering the system yet, and I can't speak for Windows machines- haven't got any

MS has released a patch today and my machine (W10) is now automatically downloading it so looks like I am an early tester.

At least you know about it, when Apple released their patch I was an unknowing tester

But that's Apple for you [shrug]

UserBenchmarks: Game 12%, Desk 31%, Work 18%
CPU: Intel Core2 Duo E8400 - 24.5%
GPU: Nvidia GeForce GT 610 - 2.3%
SSD: Crucial MX200 500GB - 38.8%
HDD: Seagate Barracuda 7200.12 500GB - 59.4%
HDD: Hitachi HDS721050CLA362 500GB - 60.6%
HDD: Seagate ST380011A 80GB - 25.3%
RAM: Unknown 4x2GB - 19.2%
MBD: MSI MS-7360

So I have installed the Cumulative Update on my Win 10 Pro 64 bit system and after I run the above benchmark. Before the patch the Desk was 28% and Work 17% although my system has been up a few days it seems faster after the reboot. I am assuming this is the CPU patch but checking on my 32 bit system Win 10 Pro no updates are available.

Can anyone confirm I have the patch on my 64 bit system?

Edit: Just been on to Windows Support Chat and the agent gave me a link, https://support.microsoft.com/en-us/help/4056892/win... which looking down the list the 7th item includes Kernel Security Update. So looks like I have the patch for my 64 bit system and waiting for 32 bit system but it seems faster!

If your update is cumulative it will not have the CPU patch on it yet until next Tuesday. At the moment the patch is only available as a stand alone download for those that want it now. It will be moved to the normal Windows update next Tuesday as part of the normal "Patch Tuesday" updates.
