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

Posted: 03-Jan-2018 | 3:56PM · 64 Replies ·

A fundamental design flaw in Intel's processor chips has forced a significant redesign of the Linux and Windows kernels to defang the chip-level security bug.

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: these changes were seeded to beta testers running fast-ring Windows Insider builds in November and December.

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, depending on the task and the processor model. More recent Intel chips have features – such as PCID – to reduce the performance hit. Your mileage may vary.

Wondering!! Since Norton service are on MS Azure maybe this could be the crux of some of the cloud issues Core is experiencing.

Microsoft's Azure cloud – which runs a lot of Linux as well as Windows – will undergo maintenance and reboots on January 10, presumably to roll out the above fixes

Windows Client Guidance for IT Pros to protect against speculative execution side-channel vulnerabilities

Summary

Microsoft is aware of a new publicly disclosed class of vulnerabilities referred to as “speculative execution side-channel attacks” that affects many modern processors and operating systems including Intel, AMD, and ARM. Note: this issue will affect other systems such as Android, Chrome, iOS, MacOS, so we advise customers to seek out guidance from those vendors.

Microsoft has released several updates to help mitigate these vulnerabilities. We have also taken action to secure our cloud services. See the following sections for more details.

Microsoft has not received any information to indicate that these vulnerabilities have been used to attack customers at this time. Microsoft continues to work closely with industry partners including chip makers, hardware OEMs, and app vendors to protect customers. To get all available protections, hardware/firmware and software updates are required. This includes microcode from device OEMs and in some cases updates to AV software as well.

The following sections will help you identify and mitigate client environments affected by the vulnerabilities identified in Microsoft Security Advisory ADV180002.

The Windows updates will also provide Internet Explorer and Edge mitigations. We will also continue to improve these mitigations against this class of vulnerabilities.

@ Krusty13,

I installed on my W7 x64 systems running NS 22.11.2.7 version, KB 4056897 from Microsoft update catalogue  https://support.microsoft.com/en-us/help/4056897, NS did not complain, and no noticeable issues so far...

Maybe you should try, for W 10, to manually update  KB's 4056892 and 4058702 and see what happens with Norton.

You should not have any issues.

Meltdown and Spectre: How chip hacks work

As technology companies race to fix two major vulnerabilities found in computer chips, the ways in which those chips could theoretically be targeted by hackers are becoming clear.

Collectively, Meltdown and Spectre affect billions of systems around the world - from desktop PCs to smartphones.

So why are so many different devices vulnerable - and what is being done to fix things?

I did just read this and the "won't get" referred to seems only to be for certain earlier versions of Windows?

BUT… you won’t get any patches installed unless and until your antivirus software sets a specific registry key.

 This is from the  linked MS article:

Windows 7, Windows Server 2008 R2, Windows Server 2012 Customers

In a default installation of Windows 7, Windows Server 2008 R2, and Windows Server 2012 customers will not have an anti-virus application installed by default. In these situations, Microsoft recommends installing a supported anti-virus application such as Microsoft Security Essentials or a third-party anti-virus application.

Note: Customers will not receive these security updates and will not be protected from security vulnerabilities unless their anti-virus software vendor sets the following registry key:

Key="HKEY_LOCAL_MACHINE" Subkey="SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat" Value="cadca5fe-87d3-4b96-b7fb-a231484277cc" Type="REG_DWORD”

Thanks to everyone that posted to this tread.  It was kind of weird as I ran Live Update this morning before I ran a Windows Check For Updates and Windows said that I didn't need anything.  This afternoon I checked the registry entry that was posted and sure enough the entry was there as described so I ran Windows Update again on my system and this time I got the download and got it applied without any issues.  I don't know whether Norton made another update to my system after the manual Live Update I ran earlier or whether Microsoft simply wasn't read to send out the update at the time I checked this morning.  Either way I'm good.

AnNe_Z On windows 10 if you have windows defender set to scan on a scheduled basis AND Norton installed Norton will take precedence because Windows disabled most, but not all the functions of Defender to avoid conflicts. Therefore the registry key will come from Norton via live updates. If you have Norton installed that update most likely has already been installed, however you can use regedit from the run command and check for the registry entry being there. According to this article Windows 7 should also receive the patches as well : https://support.microsoft.com/en-us/help/4073119/protect-against-speculative-execution-side-channel-vulnerabilities-in

"Customers must take the following actions to help protect against the vulnerabilities.

  1. Verify that you are running a supported antivirus application before you install OS or firmware updates. Contact the antivirus software vendor for compatibility information.
  2. Apply all available Windows operating system updates, including the January 2018 Windows security updates.
  3. Apply the applicable firmware update that is provided by the device manufacturer.

Windows-based machines (physical or virtual) should install the Microsoft security updates that were released on January 3, 2018."

Hi bbulog:

From Woody Leonhard's 05-Jan-2018 ComputerWorld article Win7 Monthly Rollup KB 4056894 signals early, abbreviated Patch Tuesday:

Win8.1 and Server 2012 R2 KB 4056898 is the January security-only patch, which must be manually downloaded and installed. It, too, contains only the Meltdown fix. (There was no Preview Monthly Rollup in December.) I don’t see any references to a Win8.1 Monthly Rollup — it’s likely we’ll see one sooner or later.

The How to Get This Update section of the Microsoft KB article January 3, 2018—KB4056898 (Security-only update) notes that the Win 8.1 KB4056898 update can be manually installed using the appropriate standalone .msu installer posted <here> on the Microsoft Update Catalog - just save the correct 32-bit (x86) or 64-bit (x64) .msu installer for Win 8.1 to your Windows desktop, close your browser, and double-click the file to start the installation.

You can also wait a few days for the January 2018 Patch Tuesday updates this coming Tuesday (09-Jan-2018) and a patch will likely be delivered via Windows Update by that time.

Hello

That's only part of the patching that is necessary from what I have heard. There is also a bios update which is supposed to be received from the manufacturer of your computer. I wonder what I do since my computer is custom made for me. I guess I can check the Asus website since that is the kind of motherboard I have and that is where I found other bio updates, but not recently. I think my Win 7 Pro is about 4 1/2 years old

Have a Good Night and

Thanks..

I would imagine that the manufacturer's update would be directed to any INTEL chip on the motherboard. I would anticipate that the CPU itself cannot be modified?

I'm using an ASUS/AMD motherboard dating back to the release of Windows 7 although I'm on Windows 10 now. The ASUS website does not show anything relevant and indeed officially mine may not support Windows 10!

I find Speccy invaluable in situations like this since in a few seconds it lists more technical information about your system than you could possible want to know! But in a format very easy to follow and with the bonus that you can Copy/Paste a word or bits of it so that if I can't remember the exact definition of my Motherboard, one click and I not only know it's  M4A78T-E but I can paste that into Google or the ASUS website if I need to look for something related to it.

Of course being AMD with an AMD CPU there are no INTEL chips on it so far as I can see:

Manufacturer ASUSTeK Computer INC.
Model M4A78T-E (AM3)
Version Rev 1.xx
Chipset Vendor AMD
Chipset Model 790GX
Chipset Revision 00
Southbridge Vendor AMD
Southbridge Model SB700
Southbridge Revision 00

Just in case it is useful for anyone.

Dell has a site where firmware/BIOS releases will be once they become available.

Hello, can someone tell me how to check to see if my Reg Key has the required update to install the latest Win10 1709 update? I want to know if Norton has updated this key so Windows 10 Update will not cause a BSOD when updated.  I did get the Windows update and it's pending installation. From what I understand from above, I wouldn't have received the update unless Reg Key had been updated? I just want to confirm on my laptop it has required Reg Key before proceeding.

Hello.

I tried to locate an official announcement from Symantec that Norton Security is compatible with Windows Update KB4056892.

Two of my computers running Windows 10 and Norton Security have been updated but with KB4056892 but one, running Windows 8.1 and NS, has yet to be.

Does anyone know if there are any compatibility issues with Norton Security on Windows 8.1 and Windows Update KB4056892?

Thanks.
