Security researcher Sammy Hajhamid, also known as pepsipu, announced the first software-only jailbreak for the Nintendo Switch 2, named ‘ns2jb’. The exploit targets firmware version 23.0.1 and utilizes a 32-bit integer overflow vulnerability within the SmileBASIC 4 programming application, which is backward compatible with the original console. Hajhamid reported using OpenAI’s Codex AI model to assist in identifying vulnerabilities and constructing the exploit. The jailbreak is described as ‘tethered’, requiring manual reactivation upon every console restart. While it does not yet provide full kernel access, it enables the execution of native code, the running of homebrew applications, texture modification, and save data backups. Users have already demonstrated real-time modifications in ‘Mario Kart World’, such as adding characters like Hatsune Miku and Peter Griffin.
