CPU PoC Beek said that he got the inspiration from a bug in AMD Zen processors that allowed threat actors to load malicious microcode and break the encryption at the hardware level.

Intel says that its microcode 0x129 patch must be installed via a BIOS update. While this update will limit voltage requests to a maximum of 1.55 volts, Intel says it does not significantly impact ...

Up to this point, Intel’s guidance has been a list of dense BIOS settings that could reduce performance by upwards of 9% on CPUs like the Core i9-13900K and Core i9-14900K. The microcode update ...

If retargetable microcode is new to you, imagine the instruction set of a microprocessor. If you take a look at the die you’ll find what is in effect a ROM on board, a look-up table defining ...

Microcode and micro-ops are separate things. They can be used together, but you can also have a CPU that uses microcode that doesn't use micro-ops, and vice versa.

Microcode updates also come via the operating system under Linux and Windows, but these are sometimes months behind. Linux, for example, does not yet provide any microcode updates for Arrow Lake ...

Two things are overlooked: 1) Microcode is hardware-specfic, so creating a virus that could affect a broad range of PCs at a low level is problematic, and 2) What seems easy to an expert can be ...
