Hackers could have jailbroken the PlayStation 5 thanks to a bug that was already discovered and patched on the PlayStation 4 in 2021, but then reappeared on the new console.

The bug was found by security researcher Andy Nguyen, who goes by theflow0 and has been called a “famous PlayStation hacking god” by the video game website Kotaku.
