Vulnerability found in the Apple M1 processor that cannot be closed programmatically

The Computer Science and Artificial Intelligence Laboratory of the Massachusetts Institute of Technology (CSAIL), claimed that they were able develop a PACMAN attack strategy. This is possible because of a hardware vulnerability in Apple’s M1 processor. It cannot also be closed with software.

It can be remotely carried out with both software and hardware. It is possible to access the kernel of an operating system with the PACMAN attack. However, the vulnerability could also be found in the Qualcomm and Samsung processors. This has yet to be confirmed.

Pointer Authentication is the technical part of the attack. It’s used to verify Pointer Authentication Codes, which allow only code-signed software run. The PACMAN method however allows you to choose the appropriate PAC values. This technique is similar to Specter in Intel processors.

Scott Radcliffe, Apple’s spokesperson, said that the vulnerability doesn’t pose an immediate threat to users. It is also not enough to bypass operating system protections.

An attacker can gain unauthorised access to data by exploiting a flaw in Arm processors, which was discovered a few years ago.
