Serious Spectre-class vulnerability found in Intel and Arm processors

A new Spectre-class vulnerability was found in Intel Alder Lake processors, and it was also found in the core of some Arm chips.

The vulnerability is called branch history injection (BHI). It has not been closed by any patch yet.

Theoretically an attack on the processor core via the found vulnerability allows hackers to get confidential user data, including passwords.

It should be noted that in practice the methods of attacking processors have not been recorded, they have only been proven theoretically.

Despite this, the developers have promised to release a "patch" that closes the found vulnerability.

But no one knows yet when it will be released and how it will affect the performance of the processors.
