CVE-2018-5871: Weak RNG
First published: Tue Sep 04 2018(Updated: )
In Snapdragon (Automobile, Mobile, Wear) in version MDM9206, MDM9607, MDM9640, MDM9650, MSM8996AU, QCA6574AU, SD 210/SD 212/SD 205, SD 425, SD 427, SD 430, SD 435, SD 450, SD 615/16/SD 415, SD 625, SD 650/52, SD 820A, SD 835, SD 845, SD 850, SDA660, SDM429, SDM439, SDM630, SDM632, SDM636, SDM660, SDM710, Snapdragon_High_Med_2016, MAC address randomization performed during probe requests (for privacy reasons) is not done properly due to a flawed RNG which produces repeating output much earlier than expected.
