Observe that other registers like 0x1f402016 (CDVD S Command), and 0x1f402004 (CDVD N Command), are susceptible to buffer overflows, so in overall you will find not less than 4 variant vulnerabilities like this, but Because the emulator is quasi-unpatchable, and PlayStation's bounty system stopped accepting PS2 emulator escape experiences right after the 1st a single, there isn't a purpose to locate or analyse other bugs.

Given that this expertise is around while in the retro Group - and little question in Sony's workplaces as well - it appears like Sony merely doesn't want to invest some time to existing its traditional titles at their complete most effective.

We’re ready impatiently for Section two, 404 for now – exploring arbitrary native code creating prospects from this place, as well as describing how Sony reacted to it – this getting been disclosed to them over a yr in the past website by now.
K suggests: Oct four, 2022 at five:29 am “All it wants is both a PS2-on-PS4 match or possibly a Actual physical Playstation 2 activity that includes a PS4 console compatible disc.

Regarding that intention, escaping the emulator is simply the 1st 50 percent in the chain; it’s not yet possible to jot down arbitrary native code because the application approach only has permission to map JIT shared memory as executable, and never writeable.

Due to the fact this could certainly be a route to have 10 devs at Sony deliver five hundred+ titles rather than devoting much larger groups to only get one video games or small batches Performing.
