jailbreaking the switch 2

The jailbreak for the Switch 2, known as ns2jb, is a software-only, tethered exploit. It allows running arbitrary native code as ordinary sysmodule and the built-in fs sysmodule, enabling homebrew, game modding, save file backup, and peripheral access through MMIO. The exploit was developed by Codex, who described it as the first such exploit for the Switch 2.

Using a custom Wi-Fi captive portal, WebKit has been targeted for initial code execution, though further steps are required to gain microkernel service control. Codex also explored targeting Switch 1 games and SmileBASIC, which has a known exploitable memory corruption vulnerability.
