CVE-2025-44526Public exploit

BLE service interruption via undersized PDU processing

Published Jul 9, 2025 · Updated Jul 5, 2026

Improper input validation in Realtek RTL8762E SDK 1.4.0 allows physically proximate attackers to interrupt BLE service via crafted PDUs. The BLE stack accepts data PDUs shorter than the 27-byte minimum and processes sustained streams of them, exhausting CPU, memory, and buffers. Exploitation requires BLE wireless proximity and a connection to the device; the documented result is degraded communication or temporary unresponsiveness.
