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.

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

ClientEnv component in Qualcomm Snapdragon chipsets exposes internal services 0-32 to the High Level Operating System (HLOS), potentially allowing unauthorized access to privileged operations or sensitive functions.

MitigationApply vendor firmware updates from device manufacturers; coordinate with Qualcomm for chipset-level patches.

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 the Qualcomm Snapdragon chipset model
    Check the device's system information, kernel logs, or hardware specifications to determine the exact Snapdragon chipset model (e.g., Msm8909w, Msm8996au, Sd 210, Sd 212, Sd 205, Sd 410, Sd 412, Sd 425)
    Affected if The chipset model matches any of the following: Msm8909w, Msm8996au, Sd 210, Sd 212, Sd 205, Sd 410, Sd 412, or Sd 425
  2. Verify ClientEnv component is present
    Examine the firmware image or system logs for the presence of the ClientEnv component (sometimes listed as clientenv, ClientEnv, or similar variants in firmware partitions or service listings)
    Affected if The ClientEnv component is found exposed to the HLOS in the firmware
  3. Check if internal services 0-32 are accessible to HLOS
    Review system logs, service configurations, or kernel interfaces to determine whether internal services numbered 0 through 32 are exposed to the High Level Operating System (HLOS)
    Affected if Services 0-32 are exposed to and accessible by the HLOS
  4. Confirm firmware is from the affected product line
    Check the baseband firmware version or modem firmware version reported by the device, and verify it corresponds to the listed affected products
    Affected if The firmware corresponds to any of the affected chipset models listed, since all versions are impacted

A device is affected if it contains any of the listed Qualcomm Snapdragon chipset models (Msm8909w, Msm8996au, Sd 210, Sd 212, Sd 205, Sd 410, Sd 412, or Sd 425) and runs firmware where the ClientEnv component exposes internal services 0-32 to the HLOS.
