Nintendo Switch 2 hacked: first jailbreak released

A year after launch, the Nintendo Switch 2 has its first jailbreak — a software-only, tethered exploit that requires a specific original Switch game at every boot. It uses a 32-bit integer overflow in array handling and enables homebrew, game mods and save backups on the latest firmware.
