Silicon Labs RS9116 Wi-Fi and Bluetooth Timing Vulnerability in HRNG Power Save Mode

A vulnerability exists in the RS9116 Wi-Fi and Bluetooth module related to the hardware random number generator (HRNG). When power save mode is activated, the HRNG produces predictable values due to timing limitations, potentially compromising the randomness required for secure operations.

Impact

Exploitation of this vulnerability could lead to predictability in random number generation, which is critical for cryptographic functions and secure communications. This predictability could be exploited to undermine security protocols that rely on random values.
