Tested and working on PS4 FWs 10.00-11.52 and PS5 FWs 6.00-9.60.
=== Untested - mmap issue involving pointer address misalignment leading to nothing for now ===
==== Credits ====
* Jasmine, working for Sony, for information through a WebKit commit (2022-10-19)
==== Analysis ====
* https://bugs.webkit.org/show_bug.cgi?id=246763
==== Bug Description ====
There is a mmap issue involving pointer address misalignment because of a failing assert [https://github.com/WebKit/WebKit/blob/main/Source/JavaScriptCore/heap/StructureAlignedMemoryAllocator.cpp#L94 here]. A workaround is to set HAVE_MAP_ALIGNED flag as OFF in OptionsPlayStation.cmake: [https://github.com/WebKit/WebKit/commit/626585db9857b7630cf34d82f9a0555720f15bca]. This workaround can be reverted after the mmap issue is resolved. Currently, the workaround is still enabled: [https://github.com/WebKit/WebKit/blob/ab2fff92b37e52d6c65e215b155e6b92f1646954/Source/cmake/OptionsPlayStation.cmake#L251]
OptionsPlayStation.cmake is present in the PS4 11.00 OSS WebKit source code but does not contain the HAVE_MAP_ALIGNED flag, and according to dates, this might concern only the PS5.
==== Exploit Implementation ====
==== Patched ====
'''Maybe'''
==== Tested ====
Not tested yet on PS4 nor PS5.
