As the age old question is asked once again, “Does anybody here know how to play this game?” there is trouble in Personal Computer land. It seems the fix for the Spectre security flaw in some Intel processors is worse than no solution at all. Now MS has stepped in to (at least temporarily) stop the madness:
Microsoft has released a new Windows patch to disable Intel’s hardware-based mitigation for the Spectre attack due to bugs introduced by Intel’s mitigation.
In the wake of the Spectre and Meltdown attacks that use the speculative execution behavior of modern processors to leak sensitive information, Intel released a microcode update that offers operating systems additional controls over the processor’s ability to predict branches. When paired with corresponding operating system changes, the extra controls can prevent the unwanted information disclosure.
Unfortunately, Intel discovered earlier this month that the microcode updates are causing machines to reboot.
