Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Security keys are logged when any WCDMA call is configured or reconfigured in snapdragon automobile, snapdragon mobile and snapdragon wear in versions MDM9607, MDM9635M, MDM9640, MDM9645, MDM9650, MDM9655, MSM8909W, MSM8996AU, SD 210/SD 212/SD 205, SD 425, SD 430, SD 450, SD 625, SD 650/52, SD 712 / SD 710 / SD 670, SD 820, SD 820A, SD 835, SD 845 / SD 850, SDA660, SDX20, SXR1130

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Security keys used for WCDMA call encryption are being written to system logs during call configuration or reconfiguration on affected Qualcomm Snapdragon chipsets. An attacker with access to device logs could recover these cryptographic keys and potentially compromise the confidentiality of WCDMA communications.

MitigationApply firmware updates from Qualcomm or device OEM manufacturers for affected chipsets to prevent security key logging; audit existing logs for potential key exposure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify chipset model
    Check device info or run 'cat /proc/cpuinfo' or check 'getprop' (Android) to determine the Qualcomm chipset model (e.g., Mdm9607, Msm8909w, etc.)
    Affected if Chipset matches any of the affected models: Mdm9607, Mdm9635m, Mdm9640, Mdm9645, Mdm9650, Mdm9655, Msm8909w, Msm8996au
  2. Verify WCDMA capability is enabled
    Check if the device supports or has WCDMA (3G) calling enabled - look for 'WCDMA', 'UMTS', or '3G' in radio/carrier configuration or settings
    Affected if WCDMA calling feature is active or configurable on the device
  3. Examine system logs for key exposure
    Review system logs (logcat, dmesg, /data/log/, or vendor-specific log partitions) for patterns resembling cryptographic key material appearing during or after call setup events. Search for hexadecimal strings of appropriate key length near 'WCDMA', 'call', 'encryption', or 'key' indicators.
    Affected if Logs contain any readable WCDMA encryption key material (long hexadecimal strings) in proximity to call configuration events
  4. Check log retention and access
    Inspect where device logs are stored and whether they persist across reboots. Verify if logs are accessible to apps or via adb debugging.
    Affected if Logs containing potential key material are retained and accessible beyond the call session

Device is affected if it uses any of the listed Qualcomm chipsets, has WCDMA calling enabled, and system logs contain exposed WCDMA encryption key material from call configuration events.
