Nintendo has reportedly patched the operating system exploit used in the recent Nintendo Switch 2 jailbreak with firmware update 23.5.0. According to Switch researcher OatmealDome, the update closes the entry point that previously allowed modders to access system files and dump game data.
In a post on X, OatmealDome explained that dumping and modding games will no longer be possible through the existing exploit. There may be some exceptions involving certain cartridge games and potentially game updates released in the near future.
While the Nintendo Switch 2 jailbreak has been blocked at the operating system level, some game-specific vulnerabilities remain. OatmealDome pointed to existing exploits in SmileBASIC and Civilization VI, which can still be triggered on the console.
However, firmware 23.5.0 prevents these exploits from escaping their respective games and gaining access to the wider operating system. This means homebrew applications are now restricted to whatever functionality the affected game already provides.
OatmealDome described those remaining capabilities as “not much,” suggesting that the existing game-level exploits have limited practical use without a way to access the system itself.
The update follows recent progress in the Switch 2 modding community, which had begun exploring software-based vulnerabilities in Nintendo’s latest console. One of the earlier entry points was the ns2jb tethered exploit, which worked on firmware 23.0.1 and allowed researchers to gain initial low-level filesystem access.
With firmware 23.5.0, the previously available operating system entry point has been closed, although OatmealDome indicated that some cartridge-based exceptions may remain possible for games released in the near future.
