A lot of work has been done on the recent PS5 exploit for 5.xx firmwares, the developers clearly want to advance the codes on these firmwares in order to bring the most elements. This is the case of Sleirsgoevy who has been proposing many modifications on his paylaods for a few days. He modified the code so that we can run his prosperogdb database and all the elements needed to port ps5-kstuff to firmware 5.xx. This should allow payloads to work on firmwares without a working dlsym, and here it clearly targets 5.xx firmwares.
prosper0gdb , ps5-kstuff : use crt-elf-ps5
crt-ps5: support environment with no dlsym
Add “pldldr” payload
lib: add ps5+frankenelf library
ps5-kstuff: failed performance optimization
For his part, John Tornblom has updated his SDK to add support for firmwares 2.70 and 5.xx.
Zecoxao has a new version of HEN, that allows you to load ps5-kstuff, he clarified that installing PS4 PKGs on PS5 and installing PS5 PKGs has nothing to do with security. Disabling the hypervisor will not automatically allow you to install PS5 packages, even if you have access to read and write the .text kernel. You can however use the extra power to try to disable the main a53io processor that handles PS5 packages separately, but no one has tried that yet. Not all games are supported, an increasing number of ps5 games are increasingly using the a53io kernel.
The developer Specter has just announced that ChendoChap has been working on the ROP chain under firmware 3.00, and that it would be wise to stay on a very low firmware. A year-old idea that works!
