Nintendo addresses security vulnerabilities in Switch 2
On November 10, 2026, Nintendo released update 23.5.0 for Switch 2, which not only introduced a highly anticipated feature for the Nintendo eShop but also brought challenging news for console hackers.
On October 22, enthusiasts successfully hacked Switch 2 using the NS2JB exploit, which leveraged security flaws in the SmileBASIC application and the console's operating system. Following this, hackers began porting exclusive titles from Switch 2, such as Mario Kart World and Donkey Kong Bananza, to PC and iPhone. Nintendo aimed to eliminate these exploits.
According to data miner OatmealDome, update 23.5.0 has fixed all these vulnerabilities, making it impossible to create dumps or modify games, except for rare cartridge games. OatmealDome noted that the ability to run custom software on Switch 2 is now severely limited to the functions embedded within the games themselves. However, hackers are known for their persistence in finding solutions.
The closure of these vulnerabilities was feasible due to their software nature rather than hardware. Nintendo even altered its production process for Switch but could not entirely prevent offline exploitation using the vulnerabilities. The 23.5.0 update also includes support for a digital gift system, which will be limited to family group participants and is set to debut on November 17 for Switch and Switch 2.
