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
Memory corruption while processing key blob passed by the user.

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

A memory corruption vulnerability exists in the processing of user-supplied key blobs. When malformed or malicious key blob data is passed to the affected component, improper handling leads to memory corruption that could allow an attacker to execute arbitrary code or cause a denial of service.

MitigationApply vendor-supplied patches when available. Until a patch is released, restrict access to affected components and validate all key blob input 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. Identify Qualcomm modem firmware version
    Access the modem/Baseband processor interface via AT commands (e.g., ATI, AT+CGMR) or through the device's firmware management interface to retrieve the Qualcomm 9205 LTE Modem Firmware version
    Affected if The device runs Qualcomm 9205 LTE Modem Firmware of any version
  2. Identify Qualcomm FastConnect adapter firmware
    Use system utilities (such as 'lspci', 'lsusb', or vendor-specific tools like 'iw list', ' Qualcomm Flash Tool') to enumerate wireless adapters and retrieve the Fastconnect 6200 or 6700 firmware version
    Affected if The system contains a Qualcomm FastConnect 6200 or 6700 wireless adapter with any firmware version installed
  3. Identify Qualcomm audio codec firmware
    Query the audio subsystem or use vendor tools to retrieve the CSRA6620 or CSRA6640 firmware version from the device
    Affected if The device uses Qualcomm CSRA6620 or CSRA6640 audio codec firmware of any version
  4. Identify Qualcomm Ethernet PHY firmware
    Access the network interface or use PHY management tools (such as 'ethtool', 'phytool', or vendor-specific configuration utilities) to query the Ar8031 or Ar8035 Ethernet PHY firmware version
    Affected if The network device implements a Qualcomm Ar8031 or Ar8035 Ethernet PHY with any firmware version
  5. Identify Qualcomm Aqt1000 firmware
    Check the device management interface or firmware inventory for presence of the Qualcomm Aqt1000 component and retrieve its firmware version
    Affected if The system includes a Qualcomm Aqt1000 component with any firmware version present
  6. Check for key blob processing activity
    Review system logs, crash dumps, and security monitoring tools for memory corruption indicators (crashes, abnormal memory access errors) related to key blob handling in Qualcomm firmware components
    Affected if Key blob processing is actively used and memory corruption events are observed in logs

A system is affected if any of the listed Qualcomm firmware components (9205 LTE Modem, FastConnect 6200/6700, CSRA6620/6640, Ar8031/8035, Aqt1000) are present, since all versions are vulnerable when key blob input is processed.
