==== Patched ====
 
'''Yes''' partially on PS5 FWs > 4.50 (need to test). Probably unpatched on FW 4.51 and patched on FW 5.00.
 
== WebKit exploits ==
 
WebKit exploits are harder to make and do not even give arbitrary RW because of PS5 memory protections.
 
=== Modal Browser HTTPS Bypass ===
 
* It is possible to bypass HTTPS in the modal browser, if you reply to the HTTPS CONNECT with a standard HTTP 1.1 response, instead of attempting to create a tunnel. 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.
 
==== Patched ====
 
'''No''' as of PS5 FW 5.10.
 
=== FW <= 5.50 - FrameLoader::loadInSameDocument UaF (CVE-2022-22620) leading to arbitrary RW ===
 
See also [https://www.psdevwiki.com/ps4/Vulnerabilities#FW_6.00-9.60_-_FrameLoader::loadInSameDocument_UaF_(CVE-2022-22620)_leading_to_arbitrary_RW].
 
==== Patched ====
 
'''Yes''' on PS5 FW 6.00.
 
==== Tested ====
 
Tested and working on PS4 FWs 6.00-9.60 and PS5 FWs 1.00-5.50.
 
=== FW 3.00-4.51 - WebCore::CSSFontFaceSet vulnerabilities leading to usermode ROP code execution ===
 
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.

==== Tested ====
 
Tested and working on PS4 FWs 9.00-9.04 and PS5 FWs 3.00-4.51. Untested: PS5 FWs 2.10-2.50 and >=5.00.

Discovered by cheburek3000. Released on 2023-02-07 by cheburek3000.
 
=== Bug Description ===
 
Steps:
 
1. Find kernel_pmap_store offset in kernel data segment. You can guess its location by specific signature (see guess_kernel_pmap_store_offset code). Luckily kernel_pmap_store has physical and virtual addresses for PML4.
 
2. Through physical and virtual addresses for PML4, you can find physical memory mapped directly to the kernel memory (DMAP). See PADDR_TO_DMAP macro and vmparam.h from FreeBSD for reference.
 
3. Use page tables to convert any kernel virtual address to physical address (see vaddr_to_paddr code).
 
4. Access data by physical address through DMAP.

== FW <= 4.03 - exFAT driver heap-based buffer overflow ==
 
See the [https://www.psdevwiki.com/ps4/Vulnerabilities#FW_.3C.3D_9.00_-_exFAT_driver_heap-based_buffer_overflow PS4 wiki].
 
=== Credits ===
 
Discovered by TheFloW. Disclosed by ChendoChap.
 
=== Exploit Implementation ===
 
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.

'''Yes''' in PS5 FW 4.50.

== SMAP bypass (CVE-2021-29628) ==
 
See also [https://www.psdevwiki.com/ps4/Vulnerabilities#Kernel_SMAP].
 
=== Credits ===
 
* Discovered and disclosed publicly by m00nbsd. Disclosed to SIE on 2020-12-01.
 
=== Analysis ===
 
* [https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-29628 CVE-2021-29628 (FreeBSD SMAP bypass) by m00nbsd]
* [https://hackerone.com/reports/1048322 CVE-2021-29628 (PS5 SMAP bypass) by m00nbsd]
 
=== 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.
 
=== Patched ===
 
'''Yes''' in PS5 FW 2.30 or later according to dates.

== Untested: Partial SAMU KeyRings bruteforce by missing HMAC length check in secure kernel ==
 
See [https://www.psdevwiki.com/ps4/Vulnerabilities#Partial_SAMU_KeyRings_bruteforce_by_missing_HMAC_length_check_in_secure_kernel].
 
Potentially vulnerable on PS5 FWs <= 4.03.

== Symmetric PS5 root keys dump by software exploit by Fail0verflow ==
 
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.
 
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.
