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

Buffer overflow vulnerability in WMI (Wireless Multimedia Extensions) command processing due to missing length parameter validation. An attacker could potentially execute arbitrary code or cause denial of service by sending specially crafted WMI commands with insufficient length checks.

MitigationApply Qualcomm firmware/security patches provided through OEM update channels. Contact device manufacturers for specific firmware updates addressing this vulnerability in affected Snapdragon components.

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 chipset model
    Check system information via 'lspci | grep -i network' or 'lspci | grep -i qualcomm' on Linux systems, or check the device hardware specifications. For embedded devices, examine /proc/cpuinfo or the device's technical specifications.
    Affected if The system uses any of the following chipsets: Ipq8074, Mdm9206, Mdm9607, Mdm9640, Mdm9650, Msm8996au, Qca6174a, or Qca6564.
  2. Determine firmware version
    Retrieve the wireless firmware version using 'dmesg | grep -i firmware' or 'iw list' on Linux. For embedded devices, check /etc/os-release, boot logs, or the vendor's firmware version information interface.
    Affected if The installed firmware version matches any of the affected Qualcomm products listed (all versions of Ipq8074, Mdm9206, Mdm9607, Mdm9640, Mdm9650, Msm8996au, Qca6174a, Qca6564).
  3. Verify WMI interface is active
    Check if the Wireless Multimedia Extensions interface is present by running 'ls /sys/class/net/' to list network interfaces, then examine wireless driver modules with 'lsmod | grep -i wmi' or 'modinfo wmi' on Linux-based systems.
    Affected if WMI wireless interface is enumerated and active on the system.

A system is affected if it contains any of the listed Qualcomm chipsets (Ipq8074, Mdm9206, Mdm9607, Mdm9640, Mdm9650, Msm8996au, Qca6174a, Qca6564) with WMI functionality enabled, as all firmware versions of these components contain the vulnerability.
