Switch 2’s latest system update reportedly closes the software exploit behind ns2jb, the console’s recently disclosed jailbreak. Researcher OatmealDome says version 23.5.0 patches the operating-system vulnerability. Nintendo released that update on November 9, but its version history lists accessibility changes, eShop gifting support and general fixes without identifying ns2jb.
What Did ns2jb Do?
Security researcher Sammy Hajhamid described ns2jb as a software-only, tethered jailbreak in an October 21 write-up. At the time, it worked on system version 23.0.1. The research enabled native code to run with system-service permissions, opening the way to homebrew, game modding and save backups. Its tethered setup depends on an external connection rather than remaining installed as permanent custom firmware.
If OatmealDome’s report is right, updating to 23.5.0 closes that particular route. Nintendo’s official update notes don’t name the vulnerability or describe a security fix, so the patch attribution currently comes from the researcher’s report.
What Changes for Homebrew?
OatmealDome also predicts that game dumping and modding will become impossible again, apart from some upcoming cartridge releases. That goes beyond what a reported fix to ns2jb can establish on its own. Other research may find a different entry point, and Nintendo’s changelog doesn’t describe how every homebrew method or game behaves on 23.5.0.
The developer’s write-up says the jailbreak was tethered and limited to 23.0.1 when it was published. Testing on the new firmware will show whether the reported patch blocks that method. Nintendo’s public notes describe the update’s new features and general fixes, leaving the exploit itself unaddressed.
