I dont understand.

How is the physical microprocessor buggy? Was a few microscopic curuits wired wrong?

Or is there a driver a CPU needs to function and it is whats buggy?

In a sense it is the circuits wired incorrectly, but not really at that level. The way CPUs are designed is that there's a model of their logic built in something called RTL (Register Transfer Language) which describes the logical operations that they are meant to perform. Taking X86 instructions and translating them into results is no simple task and modern processors are really hardware JIT compilers between x86 machine code and internal RISC operations. It's possible to have incorrect edge cases and mistakes in this system.

And yes, Theo and Matt are excellent programmers, but are they really so practical? All issues they have described can be worked around without excessively heroic measures, so these issues are not dealbreakers.
