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 · high confidence

A buffer overflow vulnerability exists in the DSP Service module of multiple Qualcomm Snapdragon chipsets. The issue occurs when input data is not properly null-terminated, allowing potential memory corruption. Affected components include MDM9206, MDM9607, MDM9650, MSM8909W, MSM8996AU, SD 210/212/205, SD 450, SD 615/16/415, SD 625, SD 650/52, SD 820, SD 820A, SD 835, and SDX20.

MitigationApply vendor-supplied firmware patches from Qualcomm through device manufacturer OTA updates. No user-level workarounds available; this requires coordinated firmware-level remediation.

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 chipset model
    On Android devices, run 'cat /proc/cpuinfo' or check 'Settings > About Phone' to find the chipset model. For embedded devices, check /proc/cpuinfo, or refer to device hardware documentation.
    Affected if The chipset matches one of: MDM9206, MDM9607, MDM9650, MSM8909W, MSM8996AU, SD 210, SD 212, SD 205, SD 450, SD 615, SD 616, SD 415, SD 625, SD 650, SD 652, SD 820, SD 820A, SD 835, SDX20
  2. Verify DSP Service module is present
    Check if the DSP (Digital Signal Processor) subsystem is active on the device. On Android, this may be observable through system logs, /proc/modules, or manufacturer-provided diagnostic interfaces.
    Affected if The DSP Service module is loaded and running on the device
  3. Confirm firmware version if accessible
    If manufacturer diagnostic tools or firmware interfaces are available, retrieve the DSP firmware version. Note that all firmware versions of the affected chipsets are vulnerable.
    Affected if Any DSP firmware version is present on an affected chipset (all versions are affected)

The device is affected if it contains any of the listed Qualcomm chipsets and has the DSP Service module enabled, as all firmware versions of these chipsets contain the vulnerability.
