    Superfly you could be correct but I doubt we will ever know that as a fact.

    Those kinds of things are kept very secret.

    A bios update is definitely required.

    Hi,



    I'm aware of that John (if I may call you so). But let's not forget it's a speculative exploit and that kind needs computing power to "guess" correctly.
    Still, I agree that this should be fixed. And... if it can be done without impacting performance too much then I'm all for it for sure.

    Best,
    I answer to a lot of different monikers, but John will do nicely, thanks :)

    And while it does require computing power for the speculative approach, the exploits actually take some ofthe speculation out by (as per usual) forming a bad call that breaks the chain but doesn't clear out the fill registers that have the sensitive data - which can then be dumped and analyzed. That is the real reason the exploit is dangerous - not for end users, but for cloud operators and those running lots of mission-critical VMs.

    I have been watching a lot of video's on this new problem and I'm not particularly worried. The companies that will be hit the most will be Intel and Microsoft for one good reason. They own the market share and have for a long time. Those two companies have more operating systems and CPU's out in the world than the rest put together.
    Looking at the stock market tells a story. AMD stock went way up.
    I do wonder you release the problem to the News before the updates were available.

    I won't be changing to another brand CPU. I have complete trust that Intel will solve the problem as soon as possible, with the loss of speed as low as possible. If I loose 5 % no big deal; my systems will still be super fast. If need be I will just over clock them a bit more.
    As you all can tell, I'm a Intel fan person. I have used Intel for a lot of years but I started off being a AMD person.
    When I learned more I move to Intel because of a Intel Dealer here in town. I tried Intel for CPU's and SSD's and I will stick with them.

    I believe this Flash News about this problem is way over hyped. Saying that I do want the problem fixed as smoothly as possible, now that all the hackers in the world know where to point their hacks.

    We will just get in about a week or so of a new security problem and the fix, just like we have been getting for as long as I can remember.
    The hackers are always trying new ways of screwing things up. That is what they get paid for.
    When we get security patches in Windows you will notice Microsoft never states exactly how the security problem is fixed.
    They really don't want the bad guys to know any more information.

    Just my thoughts.

    Look at the bigger picture.

    1) Intel was made aware of the Meltdown exploit back in June. at that time their stock price was running around $35 USD, on average. Then, there was a large hike (to the tune of 30%) in stock prices, starting in Late September, which took the stock prices over $45 USD. The CEO of Intel filed a 10b5-1 plan with the SEC on Oct 30, after the stock started rising, and then dumped a very large amount of stocks, minimizing the number he owns to the minimum required number for him as CEO of Intel.

    From Intel CEO sold millions in stock after company was informed of vulnerability, before disclosure - MarketWatch

    Krzanich acquired about 644,000 shares that vested at prices that varied from $12.99 to $24.17, and sold them for a weighted average price of $44.05. He also sold almost 245,000 shares he already owned at a weighted average price of $44.56, bringing his total down to exactly the 250,000-share threshold that as Intel CEO he must own as of May, as Motley Fool previously reported.

    In total, the stock sales brought in more than $39 million, according to the SEC filing, though that total does not include the amount Krzanich paid for his stock options.
    Note the date - Oct 30, a full 5 months after Intel was made aware of the exploit.

    2) The processors involved are much more far ranging than just computers and servers - what about networked medical devices in hospitals (devices that are notorious for being behind in updated software because the OEMs are and have always been lackadaisical about pushing updates as well as hospital administrators who are just as lackadaisical about applying updates because they simply do not have time / staff to do so). What about other devices, from IoT to connected vehicles to mission critical infrastructure at industries like powergrids?

    It is not over-hyped at all. The Media is making a circus out of all this, yes, but the concerns here are real.

    I agree, Intel is good... however, I think, they have been cutting corners to get the performance and now the vulnerabilities are surfacing...
    That is the good thing - "Oh, 7.25% performance hit? Well, you can simply by this new processor line that is 10% faster, and you win!"

    Class action lawsuits tend to open things like this up - and there are several already being filed.

    Here come the lawsuits! Intel sued for processor vulnerabilities - Neowin

    I hope that you are right as MSI will not update my BIOS:)
    Haswell has updated ucode for Spectre vulnerability, 23h. I tried it out. It decrease performance even further (9% on Realbench) and myself and other people that have tried it get (recoverable) WHEA internal CPU errors (none of these in 22h).

    I am back to 22h.

    Thank you John for this site.

    You would think the SEC would be looking into such a thing.

    What would happen if speculative execution was disabled completely on an Intel Core processor? Could the processor still function?

    Will older motherboards and CPU's receive bios updates?

    Well, after reading all those articles I'm finding relief, because I will have no performance impact if I decide to install the patch...
    My years of being loyal to AMD payed off, finally!

    Still I feel bad for Intel users, I'm sure there must be a way to fix this without performance loss, they deserve it after all the money they invested in an Intel CPU...

    By the other hand, what does AV software manufacturers have to say in this matter? I don't want to install a patch that will cause me a BSOD just because the kernel integration of the AV suck...
