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 checksWork through these to decide whether this CVE applies to you.
-
Identify the Qualcomm chipset modelCheck the device specifications or system information to determine the exact Qualcomm chipset model (Apq8009, Apq8053, Apq8096au, Mdm9206, Mdm9250, Mdm9628, Mdm9640, or Mdm9650)Affected if The device uses any of the listed chipset models (Apq8009, Apq8053, Apq8096au, Mdm9206, Mdm9250, Mdm9628, Mdm9640, or Mdm9650)
-
Verify the firmware versionAccess the device firmware information through manufacturer settings, boot loader, or diagnostic tools. Compare the firmware version against the affected product listAffected if The firmware version corresponds to any listed affected product (all versions of Apq8009, Apq8053, Apq8096au, Mdm9206, Mdm9250, Mdm9628, Mdm9640, or Mdm9650)
-
Confirm WMA message processing is in useDetermine if the device or application processes WMA (Windows Media Audio) format files or streams. This may be observable through audio playback activity, codec usage logs, or media application behaviorAffected if WMA message processing functionality is active or can be triggered on the device
The device is affected if it contains any of the listed Qualcomm chipsets (Apq8009, Apq8053, Apq8096au, Mdm9206, Mdm9250, Mdm9628, Mdm9640, or Mdm9650) and utilizes WMA message processing, since all firmware versions for these chipsets are vulnerable.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied firmware updates from device manufacturers (OEMs) that incorporate Qualcomm's patch for this vulnerability. This is a firmware-level issue requiring updates from the chip manufacturer (Qualcomm) distributed through device OEMs.
