PACMAN allows attackers to prevent the M1 chip from detecting software vulnerabilities.
Since the attack exploits a hardware mechanism, there isnt any trace left by PACMAN.
With PACMAN making these bugs more serious, the overall attack surface could be a lot larger.
So, how dangerous is the Apple M1 chip vulnerability?
The attack can compromise the system only when it has an existing software bug.
Future CPU designers should take care to consider this attack when building the secure systems of tomorrow.
Developers should take care to not solely rely on pointer authentication to protect their software, added Ravichandran.
The MIT researchers have disclosed their findings to Apple.
