Rs9116 Sdk
Monthly
Hardware random number generator (HRNG) in Silicon Labs RS9116 SDK versions up to 2.13.1 produces predictable cryptographic values when the wireless module operates in power save mode, enabling adjacent attackers with user interaction to compromise encrypted communications and authentication mechanisms. Vendor patch available via GitHub; no active exploitation confirmed but cryptographic weakness poses high risk to WiFi/Bluetooth IoT deployments relying on the affected module's entropy source.
