The title seems like clickbait from the article. It’s a partial exploit of the PS2 emulator inside a PS4 game that may not be patchable without removing those titles, that can lead to partial exploitation of the PS4 emulation to run other PS4 games. It does not exploit the PS5 hypervisor, so at its best allows running homebrew inside the PS4 emulator unless someone has another exploit that would lead to arbitrary execution on the PS5 - but if that was the case then this would likely be moot anyway.
