Intel CPUs Affected by LVI (Load Value Injection) Vulnerability

[engine]

A security flaw, LVI (Load Value Injection) is a new type of theoretical threat on Intel processors. The company has patched it with firmware on current models, and hardware fixes are planned for new processors model.

LVI's position in all these attacks is, technically, of a reverse-Meltdown. While the original Meltdown bug allowed attackers to read an app's data from inside a CPU's memory while in a transient state, LVI allows the attacker to inject code inside the CPU and have it executed as a transient "temporary" operation, giving attackers more control over what happens.

This flaw--together with Meltdown and Spectre--is present due to a basic design problem in the Intel CPUs where processes are fully separated on a CPU level, but temporary storage for prediction of future CPU instructions and results is not. It won't impact systems which are dedicated to one process or owner, but in our current virtual world where virtualization of processes is the norm rather than the exception, these type of flaws can be used to cause significant havoc. It is possible to peek over virtualization borders into other separated environments on the same physical server.

I don't hear of comparable problems on AMD processors. Are they so different in design or is Intel with their 69% market share in Q4 of 2019 just an easier target for security analysts?
