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 when decoding corrupted satellite data files with invalid signature offsets.

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

Memory corruption vulnerability in satellite data file decoder due to insufficient validation of signature offsets in corrupted files, allowing potential code execution or denial of service via malformed file parsing.

MitigationImplement rigorous bounds checking and validation of signature offsets before memory access operations in the satellite data decoding routine; reject malformed files with invalid offsets.

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 platform or chipset model
    Check the device documentation, system information, or firmware metadata to confirm the exact Qualcomm product name and model number
    Affected if The platform matches any of these: 5g Fixed Wireless Access Platform, Ar8035, Csra6620, Csra6640, Fastconnect 6200, Snapdragon 690 5g, Snapdragon 695 5g, or Snapdragon 7 Gen 1
  2. Confirm presence of satellite data decoder functionality
    Inspect the firmware or software stack for any satellite data processing module, such as a satellite communication handler, GNSS data parser, or satellite file import feature
    Affected if The firmware includes a satellite data file decoder or parser component
  3. Check if satellite data file input is reachable
    Determine whether the device or application can receive or load external satellite data files through user upload, over-the-air updates, or data import features
    Affected if Users or automated processes can supply satellite data files to the system for decoding
  4. Review satellite decoder bounds checking implementation
    Examine the satellite data decoder source code or binary for validation of signature offsets before memory access operations, specifically looking for bounds checking on offset values
    Affected if The decoder lacks rigorous validation of signature offsets, allowing out-of-bounds memory access with malformed files

A user is affected if they are running any of the listed Qualcomm platforms with an active satellite data file decoder that processes external files, as all versions of these products lack proper signature offset validation.
