Apple particularly surprised and continues to do so with the quality and performance of its in-house chips, notably the Apple Silicon M1.

Nevertheless, the picture darkens somewhat for the brand after the discovery of a hardware flaw by researchers at MIT.

Spotted by scientists at the MIT Comuter Science & Artificial Intelligence Laboratory (CSAIL), the flaw would have no way of being corrected, and thus recalls the hardware flaws encountered in Intel and AMD chips a few years ago.

The researchers evoked an attack scenario dubbed “PACMAN” which would allow access to the core of the M1 processors in order to obtain full access to the operating system. It would thus be possible to take control of a Mac equipped with an M1 chip by combining attacks at the software and hardware level.

The flaw would consist in succeeding in circumventing the authentication of the pointers via a speculative execution technique and passing through the last security rampart of the Apple M1 chip.

Fortunately, the attack scenario is intended to be particularly complex and researchers like Apple indicate that there is no immediate risk and that other major workarounds must be put in place before this flaw can be exploited. Users therefore have little to fear from this problem, which should be corrected in the brand’s next chips.
