Just when you thought all the faults were found, here we go again.
This time it’s the FPU that is affected. System software may utilize the Lazy FP state restore technique to delay the restoring of state until an instruction operating on that state is actually executed by the new process. Systems using Intel® Core-based microprocessors may potentially allow a local process to infer data utilizing Lazy FP state restore from another process through a speculative execution side channel.
Intel® Core-based microprocessors are affected.
Intel recommends system software developers utilize Eager FP state restore in lieu of Lazy FP state restore.
Needless to say we are becoming more and more cynical with all of the problems of late.
