GoKawiilResearcher demos partial software jailbreak of Nintendo Switch 2
Security researcher Sammy Hajhamid (Pepsipu) disclosed a software-only, 'tethered' exploit chain for the Switch 2 that achieves userland access via bugs in SmileBasic 4 and the console's FileSystem services module. The hack requires a networked macOS or Linux PC and enables homebrew, game modding, reverse engineering, save backups, and peripheral access, demonstrated with modded characters in Mario Kart World.
GoKawiil's interpretation of the reporting above, not reported fact.
The exploit chain, built using an integer overflow and buffer overflow Hajhamid says he found with help from OpenAI's Codex, shows that even newly released consoles can be probed for vulnerabilities quickly after launch. Because the hack is tethered and requires a separate computer, its practical reach may be limited for now, but it could open a path for homebrew developers and modders while prompting Nintendo to patch the flaws.
- A tethered, software-only jailbreak for the Switch 2 has been demonstrated publicly.
- The exploit chain combines bugs in SmileBasic 4 and the console's FileSystem services module.
- It currently enables homebrew, game modding, reverse engineering, and save file backups.
