In software and hardware circles, cracking and anti-cracking continued to be staged, which can be described as a struggle between technical forces. Recently, CTurt, a hacker who has been working extensively on cracking game consoles, released the latest crack which is reportedly capable of permanently hacking PS4 and PS5 consoles and cannot be fixed.
The vulnerability, named “Mast1c0re”, is implemented by exploiting a JIT compilation error used when running some PS2 game emulators on PS4 and PS5. After giving the emulator special privileges, the exploit can rewrite the source code before the PS4 code is executed at the application level.

It is worth mentioning that CTurt disclosed this vulnerability to Sony a year ago, but Sony either did not fix it or it is impossible to fix it.
CTurt said that as long as the PS5 can run PS2 games, both digitally and on disc, the vulnerability will always exist and cannot be fixed, which is determined by the design mechanism.
In fact, similar loopholes have also appeared in Nintendo’s eShop: the method adopted by Nintendo is to directly remove all 3DS games and eliminate the roots. But as of now, PS2 games can still be downloaded on PSN.
As for the impact of cracking, CTurt said that only via Mast1c0re can he do a lot of things, like run PS4 pirated games, etc., but this isn’t a perfect crack and the feature isn’t perfect. To get the final crack, deeper kernel vulnerabilities are required, but as Sony continues to issue new firmware fixes, it becomes increasingly difficult to find kernel vulnerabilities.
