Silicon Labs Bluetooth Low Energy SDK before 2.13.3 has a buffer overflow via packet data. This is an over-the-air remote code execution vulnerability in Bluetooth LE in EFR32 SoCs and associated modules running Bluetooth SDK, supporting Central or Observer roles.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
