The result was 29 microcode operations including logic, arithmetic, load, and store commands — enough to start writing microcode code. The first microcode programs written helped with further ...

The exploit allows anyone with local admin privileges to write and push custom microcode updates to affected CPUs. The same Google team has released the full deep-dive on the exploit, including ...

If you learned how to build CPUs back in the 1970s, you would learn that your instruction decoder would, for example, note a register to register move and then light up one register to write to a ...

First it might help to explain what microcode *is*. The internal hardware in a modern X86 processor does not consume X86 instructions directly. Instead, upon fetching an X86 instruction, the front ...

Unfortunately, a microcode bug—originally discovered in July but still floating around in large numbers in the wild—wrecked my good time. I eventually got my Ryzen 3700X system working ...
