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
Vulnerability of parameters being out of the value range in the QMI service module. Successful exploitation of this vulnerability may cause errors in reading file data.

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

This vulnerability exists in the QMI (Qualcomm MSM Interface) service module where parameters can fall outside their expected value range. This boundary condition issue can lead to errors when reading file data, potentially causing data corruption or unexpected behavior in the firmware component.

MitigationImplement proper bounds checking and input validation on all parameters in the QMI service module to ensure values remain within acceptable ranges before processing.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Check your Huawei Emui version
    Access Settings > About Phone on the device and verify the Emui version listed matches 11.0.1 exactly
    Affected if The installed Emui version is 11.0.1
  2. Verify QMI service module presence
    Check system settings or about phone section for QMI or Qualcomm MSM Interface component information
    Affected if QMI service module is present and running on the device
  3. Review QMI-related system logs
    Access device diagnostic logs or system event logs and search for QMI, MSM Interface, or Qualcomm-related entries for any boundary or parameter errors
    Affected if Logs show QMI parameter range errors or unexpected behavior with file read operations

You are affected if your Huawei device runs Emui version 11.0.1 AND has the QMI service module enabled, since the vulnerability requires both the specific version and the affected QMI component to be present.
