Critical BLE Buffer Overflow Fixed: How Heap Overflows Put IoT Devices at Risk

A critical heap buffer overflow vulnerability was discovered and patched in a BLE (Bluetooth Low Energy) characteristic write handler, where missing bounds checks allowed any nearby Bluetooth device to send oversized payloads and potentially execute arbitrary code. This fix adds essential buffer-length validation before memory copy operations, closing a remote attack vector that required zero authentication to exploit. Understanding this class of vulnerability is essential for any developer work
