A security researcher has demonstrated a software-only partial jailbreak of the Nintendo Switch 2 using an exploit in SmileBasic 4, gaining userland access for running homebrew, modding games, and backing up save files. The tethered exploit relies on a 32-bit integer overflow in SmileBasic's array handling, chained with a buffer overflow in the console's FileSystem services module.
Background
The Nintendo Switch 2 was released in early 2025 as the successor to the original Switch, featuring enhanced hardware and continued software security measures. Console jailbreaking has a long history, with the original Switch facing multiple exploits since launch.
