ALL CPUS ARE IRREVOKABLY FUCKED CPU is vulnerable like an open door on all intels made in the last decade and a half. AMD also suffers an obscure but patchable bug that can do the same but with great difficulty and little-no performance impact on the fix. The intel "meltdown" fix KILLS performance.
Linux mainline is already patching the shit outta this bug. Compiling it now. Initial performance figures tell that I/O on shit like NVMe has it's arms cut off at a near 50% performance reduction. Microsoft is going to push an update that will kill performance on nvidia GPUs as they utilize syscalls that are heavily influenced by the patches applied to the NT kernel.
>>>Vidya may be heavily affected.
If you choose not to patch then you can allow STUPID SHIT like inline assembly in web python or javascript to execute arbitrary code on your machine. >Interact with the internet and get fucked faster than you can sneeze.
Shit is burning. Shit is burning. Shit is burning.
Last night all audio on my computer was playing at 2% higher pitch that normal. Today it seems fine. Am I doomed?

tl;dr
Run intel? You get a performance hit! Pay 1/3 of your FPS, do not pass go.
Run nvidia with intel? Sorry sweetie, we're cutting off 2/3 now.

Dual E5-2680s were cheap.
It's bad on linux. Just warning you guys that it's gonna be worse on windows, given how poor NT kernel drivers already perform.
Patching is not optional.
Grayson Gomez
Enjoy having some javascript malware exploit this on your machine. You are basically fucked if you do and fucked if you don't just in different ways.
Adam Richardson
sorry, im not computer illiterate i know about everything on my pc
Liam Cook
Can we stop making these threads now? It's already been tested with games and there is no effect at all.
Aaron Foster
does this mean I have to upgrade to windows 10 now
Jose Sullivan
Uh, what happened?
Ryder Perry
>people use AMD Why? On every forum i read about problems like "wtf this game is so shit it cant even run properly" and they always end up having AMD shit
Samuel Wilson
Doesn't stop malicious javascript running unless you have it fully disabled. Then good luck browsing most websites nowadays. We already have even seen hiro add some shady javascript to Sup Forums only just recently as an example of a potential avenue of exploit.
Justin Turner
This is linux performance on an AMD GPU.
We have No Idea what the NT kernel will look like. Nvidia looks grim. Really fucking bad.
This is what it can do. If this shit runs in one tab of your web browser it can do T H I S. IN REAL TIME
Owen Richardson
Everything on this board always turns out to be nothing. This is nothing. You just want some excitement in your life. Play a game instead.

Amd poorfags need to fuck off back to Sup Forums nobody runs Linux apart from Sup Forums anyways

These are possibly the biggest two hardware bugs in all of human history.
Hunker down, have some fun, but keep one eye on the news.
Christopher Williams
Don't forget ARM and Android devices. Don't know about iPhone
Does this means that potential viruses could be 10x worse? Or is this only webfacing things that we can block with noscript
Robert Carter
>he thinks this is linux exclusive You might want to take another look at the problem. This is a hardware level issue that runs across all platforms.
William Edwards
No I'm not going to waste my time on a non existent problem that Sup Forums and AMD pajeet shills are spewing
Aaron Fisher
>nothing It isn't the biggest thing ever but these are some critical vulnerabilities. Even the mainstream media has caught onto it now bbc.co.uk/news/technology-42561169
Hudson Reyes
Yeah, it will piss off companies like Amazon, and annoy system admins across the country that will need to do the updating, but It isn't going to slow down your games.
Hudson Ortiz
Remember Wanna Cry exploit that NSA niggers leaked and was used by amateurs? I bet that NSA/CIA already has one for this bug and simply chose to keep it to themselves.
Brayden Reyes
Everything suffers from spectre. It's almost impossible to use.
Only intel from about 1995 suffers from meltdown, the biggun, but that's basically every gaming machine ever and quite relevant here.
It can touch your system through any means of execution and can do anything once it's in. I suggest noscripting up and avoiding as much of the web as you can stomach until you're patched.
The vidya itself is fine though.
Justin King
>finally hit 1k crypto gains >this happens >all my passwords are on my PC Come the fuck on
Landon Ross
Welp, time to buy another 1080ti and put it in SLI. That way I at least won't see a performance drop.
Dominic Martin
>Only intel from about 1995 suffers from meltdown, the biggun, but that's basically every gaming machine ever and quite relevant here. Intel was pretty smart (and shady) to lump all 3 of the vulnerabilities disclosed into one press release so they could say all CPUs are affected. Now a lot of the press and people repeating it believe they are all equally affected and all will have the same consequences.
Zachary Butler
Not to mention the CEO dumped his stock in novmeber... This is really filthy.
They've done enough damage control I think they'll actually survive.
Seems there are two issues. One, called Meltdown, only effects Intel and is bad, but the kernel page table changes everyone is making fixes it.
The other, dubbed Spectre, is apparently common to the way all processors handle speculative execution and is unfixable without new hardware.
Whoever discovered this stuff on Google’s team deserves some sort of computer security Nobel prize.
Elijah Ward
You guys do know that Hiroshimoot WILL be the first to jump on the opportunity to sell this exploit to any party willing to pay him enough to let them have personal access to every. single. computer. ever. that connects to this place, right? You're not safe here, except this time its for real.
James Sullivan
Google probably found that out by trying new ways to spy on us, they probably already infected all of us.

It allows for execution of sideloads under this high privilege. You can do anything you want.

David Peterson
>it just allows READING of arbitrary memory on the host machine Think one step further and you'll realize that if you can read anything in memory on a target machine, then you can do anything you want with that machine for any modern system.
Tyler Carter
>YOUR COMPUTER IS GOING TO EXPLODE AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA >in reality you'll probably see like a 3% decrease in performance at worst. Performance you didn't even use because 99.9% of game bottlenecks are GPU based.
Why does Sup Forums even care? They don't play games or anything.
Christian Young
Remember that NSA exploit that got used not long after it leaked and brought down critical services and cost businesses billions of dollars because they were slow to update? Ignoring critical security exploits would be stupid.
Tyler Reed
So exploding vans are now possible?

You don't count as a gamer. Don't even really qualify as a human, really.
Brody Cox
It doesn't honestly effect gaming very much, it will be bad for virtualization and database shit, end users won't be very badly effected, all the "50% reduction in performance" metrics are coming from testing with databases.
Stop freaking out.
Aiden Lopez
LMAO GUESS WHAT? I DON'T FUCKING CARE BECAUSE I DON'T HAVE A SERVER, I HAVE A GAYMEN PC AND THAT'S ALL I AND MOST OF THE NORMAL PEOPLE CARE ABOUT.

What a hit
Andrew Powell
I used to have an AthlonX4 with 3.8 GHz from like fucking 15 years ago, while I used a 1070 GTX. I upgraded it shortly afterwards to a Ryzen and know what happened? My performance only got 2-3 fps better. The idea of the CPU or mainboard being IO bottlenecks was only true before 1999, when it took like 2 minutes to copy 1.44 mb from a floppy disc or when hardware accelerating GPU's werent a thing yet.
Logan Martin
Nah, you cna download the insider preview of windows 10 with the patch right now, 0% performance change on anything
Don't fall for FUD, especially don't fall for AMD propaganda.

Isaiah Flores
So if either way I'm fucked. What am I supposed to do?
Sebastian Perez
AMD is trying to take advantage of media misreporting, that's really it. The fucking Spectre exploit was literally first proven on a Ryzen and it is a more serious exploit than Meltdown in the first place, but the media is only reporting Meltdown for whatever reason.
As much as I think Intel are Jews (I mean I'm using an AMD CPU right now) they are not helping anything by lying to the public about being exempt from the coverage of this exploit, it is dangerous if anything.
Chop your PC up with an axe and go live in the woods
Michael Morales

Mason Gutierrez
Exploding vans are unlikely, but almost invisible malware scraping all your login details is very possible and more notably virtual machines on the same host will be able to fuck with each other, which is all kinds of extremely fucking bad.
Carter Robinson
this exploit in no way allows for WRITING or EXECUTION of any sort. it allows for READING of information, jesus fucking christ people. >goal post
Thomas Baker
specter bug is fixable by software, nothing to worry about.
Eli White
Nice
Camden Ramirez
Meltdown allows full access to Level 0.
Angel Martin
compared to asshole wide meltdown that affects all Intel chips in the past 20 years, yeah
Cooper Nelson
Its not that serious, you would have to have system access to use the exploit.
Its just a bunch of technological illiterate retards from Sup Forums and linux boards trying to justify their jobs by hyping something that happens all the time, exploits are found and patched routinely.
The patch to the theoretical exploit was already written and finished months ago.
Lincoln Nelson
No. It is not fixable not even by HW.
Christopher Gonzalez
>this kills the AMD pajeet
just think, all those idiots who bought a Ryzen and wasted their money got themselves so excited for a day.
It's almost adorably pathetic.
Josiah Torres
thank you for letting everyone know you know absolutely nothing about what you are talking about and are just citing retarded Sup Forums and Sup Forums posters! this.
Jordan Sullivan
Fucking AMD shills working overtime.
Fix only affects high syscall operations.
OSX was already patched months ago, Sup Forums runs on Macs, noticed any difference? Yeah, thought not.
Joshua Hall
It's far more difficult to mitigate than simply removing a feature like with Meltdown, it is more serious in that regard. Meltdown is officially impossible to execute after these patches are applied, Spectre is far more complicated with regards to mitigation and nobody really knows exactly how to prevent it yet, it is going to cause more harm than Meltdown ever could because it is not so trivial to solve.
Easton Johnson
>you need system access and you need to be able to run malicious code to do this theoretical exploit
This is what you idiots are getting worked up over? Jesus christ you're literally worse than boomers trying to use a computer.
Robert Howard
What the fuck is going on
Luke Parker
I'm scared
Benjamin James
>Have to upgrade to FF shitty quantum That was the breaking point for me to switch to Waterfox, and it's been a great experience so far other than an odd thing where a couple sites can't be reached due to apparently using an older form of data transfer that WF doesn't support due to security. Plus having tabs on bottom is a fucking BUILT IN OPTION, YOU HEAR THAT MOZILLA? STOP FUCKING WITH THAT SHIT.
Seriously, check out that shit or Pale Moon, heard good things about that as well.
William Wilson
Spectre is architectural and you're not getting the "way the fuck harder to execute" you have to change everyones shit then
Leo Bennett
thanks bro, i'll check it out.
Jacob Bailey
The fear is over cloud computing, this is pretty much the worst thing that could possibly happen to a cloud service, nothing is guaranteed to be totally sandboxed anymore.
If you didn't fall for the cloud meme, the only impact this will have is the performance penalties of the patch.
Ethan James
Intel's CPUs manufacture for the past 9 yrs have a massive security flaw in the them whose fix is gonna tank at least 1/5th of their performance.
Caleb Morgan
t. Schlomo. 30 fucking percent
Jaxon Williams
God damn that looks good.
Jacob Bennett
> fix is gonna tank at least 1/5th of their performance. no it isn't, you are retarded.
Brayden Johnson
A question to the computer litterate crow, could this architecture flaw be exploited in a ring 0 exploit, and if so, are the exploits undetectable by antiviruses?
Henry Lopez
Has Microsoft already patched this for Windows 7?
Caleb Taylor
if hackers had system access to your cloud you have way worse things to worry about than them being able to read two lines from your kernel lmao
the only thing that has been confirmed about this is that people had to bring their shit down to patch
Robert Collins
>a ring 0 exploit AFAIK the exploit allows ring 3 code to read ring 0 memory, and that might include passwords. >antivirus Antiviruses are a meme.
Daniel Rogers
yup, that's the main issue
Grayson Ross
my pc is a pre-built that i bought at the end of 2009, am i fucked?
Jace Hughes
no, end users will not notice a thing.
Lincoln Davis
Nothing is happening, benchmarks are normal as usual and if you are a sysadmin just uodate your shit. END
