The browser will just display that response. The downside to this is you have no idea what the contents of even the HTTP REQUEST would have been, but it is useful for directing the web browser to any website you want. | ||

Contrarly to PS4, on PS5 this exploit does not allow arbitrary usermode memory RW because of PS5 memory protections. However thanks to tricks it is possible to get usermode ROP code execution from this exploit. | |||

Not yet because even though there is ChendoChap's method to execute usermode code in WebKit, there is no PS5 kernel dump to build a kernel ROP chain. Exploiting this kernel vulnerability blind is almost impossible because once the USB device is inserted it corrupts the kernel heap memory and if the offsets in the kernel ROP chain are bad it creates a kernel panic. | |||

=== Bug Description === | === Bug Description === | ||
A SMAP bypass has been found by m00nbsd while working on FreeBSD 12. It is named CVE-2021-29628 and affects FreeBSD 12.2 and later (til it was patched). It does not work on PS4 because PS4 kernel is based on FreeBSD 9 which did not contain the vulnerability and because PS4 SMAP does not come from FreeBSD but is custom from Sony. It used to work on PS5 before it was disclosed and patched. | |||

See | See [https://twitter.com/fail0verflow/status/1457526453105569793 Fail0verflow's announcement on Twitter (2021-11-08)] | ||
Fail0verflow either has a bootrom execution exploit or an AMD/ARM PSP hack. | |||
''It is speculated that this exploit is a derivative of the ZenBleed [https://nvd.nist.gov/vuln/detail/CVE-2023-20593 CVE-2023-20593] exploit, as the PS5 APU is a custom ZEN 2 Ryzen chip.'' | |||
This allows to decrypt on PC most parts of the PS5 System Software files including: | |||
* PUP | |||
* secure loader (?AMD? ARM Platform Security Processor module) of Oberon | |||
And by derivation, mostly like on PS Vita: | |||
* secure modules | |||
* kernel boot loader / BIOS | |||
* non-secure kernel | |||
* usermode system modules | |||
Potentially unpatched. | |||

== Untested: ZenBleed (''[https://nvd.nist.gov/vuln/detail/CVE-2023-20593 CVE-2023-20593]) leak register contents directly from the CPU.'' == | |||
This is a well documented CPU vulnerability in AMD Processors with the Zen 2 microarchitecture. There is no proof of concept specifically for the PS5, however we do know the PS5 uses a custom Zen 2 chip. This is a hardware bug that uses software to exploit the system. AMD has since patched this with [https://www.amd.com/en/resources/product-security/bulletin/amd-sb-7008.html software], but we are unsure of the status for the latest PS5 firmware (assumed to be patched).
