It seems the x86 architecture is once again afflicted with a flaw that arises out of unsafely implemented accelerations, namely the just-releaved Zombieload vulnerability.
We know that Zombieload is possible when Hyperthreading is enabled. Here is a question: Is it possible to disable Hyperthreading not for all cores in the BIOS but rather on a per-core basis programmatically from the OS or from the bootloader? I ask because if this were possible, then it would be reasonable to segregate the sensitive code i.e. the kernel and the major daemons into one core that has Hyperthreading enabled, and then run all other (risky) user processes on the other cores, which have Hyperthreading disabled. Cheers.
