Overview

Affected versions of this package are vulnerable to Integer Overflow or Wraparound due to improper packet processing by the le_advertising_report function in /subsys/bluetooth/controller/hci/hci.c. A malicious BLE device can cause a buffer overflow by sending malformed advertising packet to a BLE device, leading to DoS or potential RCE on the victim BLE device.
