Nintendo Switch Vulnerability Allows Attackers to Run Unauthorized Code on Your Console
Nintendo patched CVE-2026-82079, a CVSS 7.0 stack buffer overflow in original Switch local wireless allowing nearby code execution via QR-code workflows.
Nintendo patched CVE-2026-82079 (CVSS 4.0 base score 7.0, High), a stack-based buffer overflow in the original Switch's local wireless networking affecting firmware earlier than 23.0.0. An adjacent attacker must scan a QR code displayed by the console, via the Album "Send to Smartphone" feature or Mario Kart Live: Home Circuit, before crafted packets can corrupt memory and enable return-oriented programming for arbitrary code execution. EPSS is approximately 0.16%, Switch 2 is not affected, and Nintendo's advisory was published September 10, 2026.
