M1 chips developed by Apple suffer from a security flaw. Called M1RACLES by the developer looking for it, the breach allows the two applications to communicate and exchange data without having to pass through the macOS function. The researcher believes that the defect is not very dangerous and should not be corrected by Apple.
Hector Martin, a developer and researcher in computer security, discovered a security flaw in the architecture of ARM processors designed by the famous M1 chips Apple Silicon. Entitled to M1RACLES, For “M1ssing Register Access Controls Leak EL0 State”, the violation pertains to all devices powered by M1 processors, such as the iMac 2021, iPad Pro 2021, the latest MacBook Air and MacBook Pro.
“A flaw in the design of the Apple Silicon M1 chip allows any two applications running the operating system to secretly exchange data with each other without using memory, sockets, files, or other common functionality of the system . Operating System” Hector Martin explains this flaw posted on the website.
A security flaw that Apple shouldn’t fix
If the researcher acknowledges that the severity of the defect remains moderate, it believes that it could theoretically allow two malicious software already present on the machine to exchange data without triggering an alert. Additionally, the flaw may allow an attacker “Bypass some of the most stringent privacy protections” Within Apple Software.
Nevertheless, Hector Martin suggests that Violation is of very limited danger. Using it alone may not actually put Apple computers at risk. As a precaution, the developer contacted the Cupertino company to inform them of its discovery.

The researcher noted that it is impossible for Apple to fix the breach with changes to the software of its operating system. Apple must have Chip hardware interference. For now, there is no indication that Apple intends to fix this failure on its next chips, the M2 processor. As the developers point out, there is no real cause for concern.
