ns2jb is a software-only jailbreak for the Nintendo Switch 2 running firmware 23.0.1, announced in a post on X. It runs arbitrary native code, allows save dumping, reverse engineering and game modding, and reaches most peripherals via MMIO. It is tethered (rerun after reboot) and gives no CFW or full kernel control. The post says Mario Kart World has been modded with custom characters. It gives no technical detail on the exploit chain.

TL;DR Announces ns2jb, a tethered software-only Switch 2 jailbreak on firmware 23.0.1 that runs arbitrary native code without a modchip.
