Huge Intel CPU Bug Allegedly Causes Kernel Memory Vulnerability With Up To 30% Performance Hit In Windows And Linux

If the reports are accurate, it appears that Intel might have a pretty severe chip-level security bug on its hands that cannot be simply swatted away with a microcode update. The bug affects all modern Intel processors dating back at least a decade.

We should note that squashing the bug requires a patch at the OS level; and Linux patches have already been distributed (with redacted comments). Microsoft is expected to address the bug in its monthly Patch Tuesday update. The circumstances surrounding the exploit are currently under embargo, but some details are starting to make their way to the public spotlight, thanks to reporting over at Python Sweetness and The Register.

I started on computers back in the days of the Sinclair ZX81 and Spectrum, back when people were coming to terms with how great their new digital watch was. Even though I worked in DIY Shops, Fancy Goods, the building trade, DJ'ing etc, my main interest and passion was always in coding, graphics and games. I decided to take the plunge into computer shops in the mid 90's and in 2003 set up my own computer business. I have a simple work ethic which is I prefer to make a little money often, rather than charging a fortune and losing customers. This has proven to work for me and my customers. In all the years I have traded I have never advertised and yet each week, I get new customers through recommendations - there is no higher praise :)
