🚨 PS5 14.10 / 14.00 EXPLOIT UPDATE: BROWSER CONQUERED. HYPERVISOR NEXT. 🚨 The WebKit browser is fully compromised. A newly weaponized FontFace Use-After-Free (UAF) flaw is actively leaking memory pointers, defeating the browser's ASLR security randomization. Paired with the recent Canvas read/write exploit, userland is officially wide open. Now, the final boss. The exact security walls of the PS5 have been mapped. A request was sent to the kernel to allow custom code execution, and the kernel actually approved it. But the hypervisor secretly stepped in and stripped the execute rights away. The kernel is literally being lied to by the hardware layer underneath it.  This proves injecting raw custom code (shellcode) is blocked at the hardware level. The roadmap is 100% clear: the jailbreak must use ROP to hijack the system's existing code.  Firmware 14.00: The absolute prime target, 14.10 introduced heavy mitigations that locked down multiple kernel pathways. 14.00 sits in the sweet spot with a much wider unpatched attack surface including potential hypervisor vulnerabilities that were sealed shortly after. Firmware 14.10: Sony locked multiple known avenues behind dead boot switches here, but the door is now kicked wide open via the WebKit exploit. The hunt has officially pivoted to a fresh kernel bug. For the nerds: Browser ASLR is defeated via the FontFace UAF (p563), which reclaims a freed CSSFontFace object with a 192-byte ArrayBuffer to leak browser heap pointers. For the kernel: Sys 588 requested RWX on GPU pages, returning success (0), but sys 547 confirmed protections clamped to RW. The Hypervisor enforces W^X below the kernel, ensuring the PTE never receives PROT_EXEC. Finally, the earlier AIO double-free claim is officially retracted; two racing calls reporting success is a double status, not a demonstrated double-free, completely nullifying the proposed exploit chain
