Whether it is the software or hardware circle, between crack and anti-crack, it is always a game of cat and mouse. A few days ago, CTurt, a hacker who has long been dedicated to game console cracking, announced the so-called permanent vulnerability of PS4 and PS5 consoles, and he believes that the vulnerability named “Mast1c0re” cannot be fixed.
The vulnerability exploits a JIT compilation error used to run certain PS2 game emulators on PS4 and PS5, thus giving the emulator special privileges to rewrite the source code before executing the PS4 code at the application level.
In fact, CTurt disclosed the vulnerability to Sony a year ago, but he stressed that Sony did not fix it, or could not fix it.
The hacker stressed that the vulnerability will exist as long as the mechanism that allows the PS4 to run PS2 games (digital or CD-ROM) exists, which is determined by the design mechanism.
Previously, a similar vulnerability appeared in Nintendo’s eShop, which has removed all 3DS games. However, as of this writing, PS2 games are still available for download on PSN.
About cracking, CTurt said that Mast1c0re can already do enough things, such as running PS4 pirated games, just to achieve the perfect crack, but also need the support of the kernel vulnerability, just as Sony continues to issue new firmware, the difficulty of finding kernel vulnerability is getting higher and higher.
