Name of the Vulnerable Software and Affected Versions: Snapdragon (Automobile, Mobile, Wear) versions IPQ8074, MDM9206, MDM9607, MDM9640, MDM9650, MSM8996AU, QCA6574AU, SD 210/SD 212/SD 205, SD 425, SD 427, SD 430, SD 435, SD 450, SD 625, SD 820A, SD 835, SD 845, SD 850, SDA660, SDM429, SDM439, SDM630, SDM632, SDM636, SDM660, SDM710, Snapdragon High Med 2016

Description: The issue is related to a flawed Random Number Generator (RNG) that produces repeating output earlier than expected. This affects the MAC address randomization performed during probe requests, which is not done properly.

Recommendations: For Snapdragon (Automobile, Mobile, Wear) versions IPQ8074, MDM9206, MDM9607, MDM9640, MDM9650, MSM8996AU, QCA6574AU, SD 210/SD 212/SD 205, SD 425, SD 427, SD 430, SD 435, SD 450, SD 625, SD 820A, SD 835, SD 845, SD 850, SDA660, SDM429, SDM439, SDM630, SDM632, SDM636, SDM660, SDM710, Snapdragon High Med 2016, consider disabling the MAC address randomization feature until a proper fix is implemented to address the flawed RNG issue. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
