CVE-2025-44531Public exploit

BLE connection denial via premature Pairing Random

Published Jun 24, 2025 · Updated Jul 5, 2026

Denial of service in Realtek RTL8762E SDK 1.4.0 allows physically proximate attackers to block secure BLE connections. The BLE Secure Connections state machine processes a Pairing Random packet before the required Pairing Public Key exchange, enters an invalid state, and aborts pairing. The attack requires Bluetooth range and no prior authentication; repeated packets prevent the RTL8762EKF-EVB from establishing secure BLE connections.
