What is CVE-2025-10457?

This vulnerability arises from the function that manages Bluetooth Low Energy (BLE) connection responses, failing to check if a response is anticipated. Instead of validating whether a connection request was initiated by the device, it only relies on matching identifiers. This can potentially allow unauthorized devices to connect without proper verification processes, leading to security threats within the BLE ecosystem.
