    Intel CEO Krzanich sold shares after company was informed of chip flaw - Business Insider

    Intel was aware of the chip vulnerability when its CEO sold off $24 million in company stock before the bug was made public.

    Hiya,

    It's not just Intel and not all Intel processors have the security risk. AMD, AWS, Nvidia also have the out of order execution branch process model, some of these are on the list too. The most popular Intel chip to have the issue is the "core" desktop/mobile CPU's such as i3, i5 and i7, some Xeon's and a few others.

    The sky isn't falling here, for the most part, the performance hit for most end user systems is anticipated to be about 5 to 10% on some applications, not all.

    The laptops I have are affected however, the Intel based HP Proliant servers and ARM based NAS arrays I have are not affected.

    Here is some more technical reporting of the issue rather than sensationalized:

    CVE - CVE-2017-5753

    Because my Xeon processors aren't in the list of the affected products. Like I said in my post, not all Intel CPU's have this issue, it appears that mainly the processors used for end user desktop and graphic processing, as far as I can tell at this point, are the ones most affected.

    As my Proliants are running a Linux based hypervisor and have no GUI, I didn't spec the boxes with processors that are optimized for graphics and GUI's.

    From the Intel support KB:
    ===========================================
    Summary:
    In response to issues identified by external researchers, Intel has performed an in-depth comprehensive security review of our Intel® Management Engine (ME), Intel® Server Platform Services (SPS), and Intel® Trusted Execution Engine (TXE) with the objective of enhancing firmware resilience.

    As a result, Intel has identified security vulnerabilities that could potentially place impacted platforms at risk.

    I'm sure he'll have a good explanation for that coincidence.



    Note: Ran across some speculation that it's an NSA *built into the chip* backdoor that hackers stumbled upon.

    From what's known currently, it's not a hardware "backdoor", it's an attack that leverages code in the OS that accesses the out of order execution branch, (normally used to optimize performance in predictable outcome instruction sets), the vector goal is to read/write from/to system memory with elevated perms.

    If you want to have you hand at the NSA toolkit Vault 7:

    Happy reading.... :-)

    The flaw is in the Intel x86-64 hardware and it appears a microcode update can't address it. It has to be fixed in software at the OS level, or go buy a new processor without the design blunder.

    From what I read, the OS level *fix* will cost a 10% to 15% performance hit.

    The dust ain't quite settled yet, however.

    Crap sometimes just happens, but then again, sometimes crap is planned from the get-go.

    I was on a call today where 30% performance hits have been reported. All depends on the workload the server is running.
