Switch 2 software-only jailbreak ns2jb and its attack chain published
What happened
On October 22, Hacker News' front page covered the Switch 2 jailbreak tool ns2jb and a technical breakdown of it. The tool targets Switch 2 running firmware 23.0.1 and is software-only, but it has to be re-triggered. The developer walks through the attack chain: it starts from a SmileBASIC bug, gains arbitrary read/write in fs, then reaches code execution. Per the report, ns2jb runs native code with the privileges of any ordinary system module and the built-in fs system module, enough for homebrew, game mods and save backups. What's public so far is the jailbreak capability and the attack chain explanation.
