Kernel-memory-leaking Intel processor design flaw forces Linux, Windows redesign
Speed hits loom, other OSes need fixes.
A fundamental design flaw in Intel's processor chips has forced a significant redesign of the Linux and Windows kernels to defang the chip-level security bug.
...
Bear in mind there are two flaws at play here: one called Meltdown that mostly affects Intel, and what the above article is all about, and another one called Spectre that affects Intel, AMD, and Arm cores.
Was just notified of this news item a minute ago. It seems rather significant, as the CPU security flaw can not be fixed with microcode it requires operating system patches, but possibly with up to 30% loss of net processing power.
