Switch 2 jailbroken, can run homebrew
Researcher Sammy Hajhamid exploited a 32-bit integer overflow vulnerability in SmileBasic 4 to jailbreak the Switch 2 and demonstrated running homebrew. Using OpenAI's Codex to probe the SmileBasic interpreter, he spent two weeks discovering the vulnerability, thereby gaining arbitrary read/write access. SmileBasic 4 has been removed from the Switch eShop, and the vulnerability may be fixed in a subsequent firmware update.

Researcher Sammy Hajhamid used a software vulnerability to jailbreak the Switch 2 and was able to run homebrew programs. The jailbreak exploited SmileBasic 4, a programming environment and interpreter designed to run specifically on Nintendo hardware. Hajhamid used OpenAI's Codex to probe SmileBasic's language interpreter, spending two weeks to discover a 32-bit integer overflow vulnerability that allows read and write operations on portions of system memory. Building on this, he found other vulnerabilities from within the Switch 2 and escalated privileges to gain arbitrary read and write access. He then demonstrated running homebrew programs on the jailbroken console. SmileBasic 4 has been removed from Nintendo's Switch eShop, and the vulnerability may be fixed in a subsequent firmware update.
