A new vulnerability has emerged in Apple processors

Hardware-based vulnerabilities such as ‘Spectre’ discovered in AMD and Intel chips have become a major problem for today’s chipmakers. Now, although it is not as dangerous as Specter, a new vulnerability has been discovered in Apple processors.

It can affect many chips

The new vulnerability, which is called ‘Augury’ by researchers and affects Apple’s M1, M1 Max and A14 processors, works against Specter, which works by monitoring what data the core and instructions access. reportedly invalidates the defense.

However, taking advantage of the use of Data Memory Dependent Prefetcher (DMP), an optimization that takes into account the contents of previous memory preloads of Apple silicon, Augury makes it possible to leak data with this method, which provides a clue about the contents of the memory.

Saying that Augury can reach old A-series chips and newer M1 solutions and sent all the findings to Apple, the researchers said that the vulnerability is not as dangerous as Specter, but ASLR is not as dangerous as Specter. (Address Space Layout Randomization).
