CVE-2018-5871 — Qualcomm Mdm9206 Firmware security vulnerability
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.

Matched remediation archetype
Cryptography, certificate, signature, and channel validation
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Inventory affected algorithms, key uses, trust stores, certificate validation settings, random sources, and plaintext channels across clients and services.
- Determine which secrets, identities, signatures, or data protections depend on the affected primitive or validation path.
- Check debug, compatibility, fallback, and hostname or audience override settings in build and runtime configuration.
Remediate safely
- Use a maintained platform cryptographic API with approved algorithms, modes, parameters, randomness, and full peer identity validation.
- Remove insecure fallback and validation bypasses; separate keys by purpose and load them from managed secret storage.
- Plan rotation or reissuance for affected keys, certificates, tokens, hashes, or ciphertext and document compatibility sequencing.
