PS5 WebKit Also Affected by Use-After-Free Vulnerability (CVE-2021-30858)

Since testing of the Use-After-Free Vulnerability (CVE-2021-30858) in the PS4Scene indicated the bug is present in the PS4 WebKit, several in the PS5Scene also gave the Proof-of-Concept Test a try with the PS5 OSS WebKit on a PlayStation 5 console including @cedsaill4 (aka Cedsaill2 on Twitter) and @yyoossk (aka Cloud0835 on Twitter) with some positive feedback as well in the Tweets below.

While many are still battling PlayStation 5 Scalpers to actually obtain a console for testing Private PS4 Exploits in hopes of a PS5 Jailbreak, below are some previous articles sorted by date with the oldest first for those new to the scene:
