Limited out-of-bounds write via Bluetooth
Published Sep 26, 2023 · Updated Nov 4, 2025
Bluetooth in Apple OS releases before iOS 17, tvOS 17, watchOS 10, and macOS 14 allows physically proximate attackers to write out of bounds. Apple identifies Bluetooth as the component and improved checks as the correction, but has not disclosed the faulty code path or input. Exploitation requires physical proximity; the published impact is limited to an out-of-bounds write, with no documented code execution or service interruption.

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.
