What is the Meltdown bug?
Most of the bugs that make the news are software bugs, but the Meltdown bug is a hardware bug (in the form of a design flaw) that affects Intel processors going back several generations. In a nut shell, the Meltdown bug is a brand new way to (possibly) steal your information.

I suspect based on what I have already read (likely incomplete) that the vulnerability is a lot harder to exploit than what the hype would seem to indicate. I also suspect that good infosec practices will likely make this near to impossible to exploit as the descriptions provided so far, require the execution of code to exploit.
However, having said that, shame on chip manufactures for allowing this vulnerability to even exist.
It’s like Apple’s battery thing but affecting every Intel chip, not just the old ones.
30% performance hit across the board after the OS fixes are applied. Not happy.
Maybe I am sound off the wall but a slowdown in performance just after the internet neutrality deal in which we are to experience slowdowns if we stream online????
Hmmmmmmmm...........
What if............?
Nah! Skip it!!!!!!!!!!!!!!!!!
Never Hotchee....Right! .......Right???
;)/;...........
So.....in order to ‘fix’ a hardware problem in the Intel processors it is necessary to write code for operating systems?
We just got one of our kids an older Apple phone for Christmas, I was so upset to hear about that Apple thing. Disgraceful.
Bug or feature?
I don’t know about you but I seem to recall rumors that our intelligence and law enforcement community have long wanted backdoors into any data system.
Seems to me this “bug” is rather made to order for that purpose. The others bugs too. And they seem to date back to the correct time frame for the rumors: the Clinton Administration.
Unless you believe in coincidences that are way too convenient by half.
I wonder what they would have done with these had Hillary won? Why reveal them now?
I know, tin foil hat stuff. It’s not like they wouldn’t want Trump to have access to them but would Hillary.
How to protect your PC against the major ‘Meltdown’ CPU security flaw
Harder to do a recall of 20+ years worth of processors than it is to write software to work around the bugs.
Even the recent generations (2010+) would be a hard sell.
bkmk
Yep. Not a bug. A feature, and now that its been outed, its a bug, and a crisis for Intel.
Wrestle with pigs, you get dirty.
The Meltdown issue can now be patched against by getting an update from your PC manufacture or Mother Board manufacturer.
Asus definitely has it covered. Asus lists it under Bios updates. Sometimes called MD update.
Thanks for the link.
can you imagine buying a high performance vehicle, only to later be told that there was a design flaw that needs to be fixed but you’ll lose 30% performance?
Yes, because of the way the OS enables/enabled the CPU to perform protected memory operations on its behalf. A vulnerability was discovered that enables "malicious code" as simple as Javascript to access the protected memory in the CPU.
The OS patch disables the OS kernel from allowing the CPU to perform protected memory functions that are vulnerable and move those functions to the OS by creating separate memory tables for the OS to access.
That results in the performance hit some are reporting.
I'm not sure the performance hit is 30% as some say,I've not seen any benchmarks proving that.
Simply attesting a performance hit may be enough to boost future sales.
I would note that an AMD spokesman, addressing these features/bugs, said that AMD chips aren’t affected by all of the bugs.
The all aspect caught my attention.
Can’t let Trump play with the Clinton toys.
OK it states linux is going to be ‘easy to hack’? What do we do to protect against it? Just update firefox? Will linux issue an update too? What is going to slow down performance? Just the windows os update?
