## Key points

- A software exploit gives Switch 2 hackers partial homebrew access.
- The tethered method uses flaws in SmileBasic and FileSystem services.
- It works on firmware 23.0.1 but may be patched soon.

## Summary

A researcher has demonstrated a software-based, partial jailbreak of Nintendo’s Switch 2, enabling homebrew software, game modifications and access to some system features. The exploit shows that hackers have found weaknesses in the console’s software, although it does not give them full control of the hardware.

The tethered method uses an integer overflow in the Switch version of SmileBasic 4, followed by a flaw in the console’s FileSystem services; it also needs a macOS or Linux computer on the same network. The researcher demonstrated modified characters in Mario Kart World, but the exploit remains limited to a userland sandbox. SmileBasic has been removed from the Switch eShop, and Nintendo may patch the vulnerability in an upcoming firmware update; the method works on firmware 23.0.1.
