“Heart” of top-of-the-line products Apple, like MacBooks, iMacs and even models of iPad Pro, the M1 chip has a factory-installed and irreparable security breach. The discovery was announced by developer Hector Martin, and was reportedly acknowledged by the company itself, which, according to him, admitted that there is no simple way to solve the problem, such as a simple software update.

According to the developer, the flaw discovered in the M1 allows two apps to secretly exchange data without using the operating system’s normal features. “If you already have malware on your computer, that malware could communicate with other malware on your computer in a way you wouldn’t expect. It could probably communicate in a variety of ways you’d expect anyway,” he explained. to Phone Arena.

According to Hector Martin, however, the security flaw will not put confidential data of users using devices at risk. Apple with the M1 chip. According to him, this security risk would only allow advertisers to track across apps, and cannot be used by hackers to take control of a device or even steal sensitive information.

“Honestly, I would expect advertising companies to try to abuse this sort of thing for cross-app tracking more than criminals. In fact, no one is really going to find a nefarious use for this flaw in practical circumstances. Covert channels can’t leak data from uncooperative apps or systems,” he warned.

A14 Bionic and M1X

Even without any real threat to user data, the security flaw in the M1 chip exists and, according to the developer, will only be fixed in the next generation of the processor. This means, in other words, that it will affect the M1X, set to equip the next MacBook Pro.

Hector Martin also reported that the detected problem could even cause problems with the A14 Bionic, which is under the hood of the iPhone 12. This would happen because the processor of the flagship Apple It is built on the same CPU microarchitecture as the M1. According to the developer, one way that could potentially fix the flaw would be to run the entire operating system as a virtual machine (VM), but this is not seen as a viable solution to the problem.
