Proximity-based code execution via local wireless stack overflow
Published Sep 10, 2026 · Updated Sep 11, 2026
Stack-based buffer overflow in Nintendo Switch before 23.0.0 allows physically proximate attackers to execute arbitrary code. The local wireless networking functionality writes crafted network traffic beyond a stack buffer, enabling ROP control flow. The attacker must be within wireless range; successful exploitation runs unauthorized code on the console, while no separate data-access or service-impact bounds are published.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
