Default Intel denies chip design stuff-up

Intel has denied that there is a huge design problem with its chips which will mean a patch which could slow down its offerings by between five and 30 percent.

Yesterday we reported that the flaw appeared to be in the Intel x86 hardware, and a microcode update can't address it. It allows normal user programs to snuffle the contents of protected kernel memory. The fix is to separate the kernel's memory entirely from user processes using what's called Kernel Page Table Isolation, or KPTI. But this will slow things down a lot.
