Vulnerability Summary

The Bluetooth Classic implementation in Espressif ESP-IDF 4.4 and previous versions does not properly handle the reception of multiple LMP IO Capability Request packets during the pairing process, allowing attackers in radio range to trigger memory corruption (and consequently a crash) in ESP32 via a replayed (duplicated) LMP packet.
