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
How this class of weakness works · CWE-20

The application accepts input without confirming it is well-formed or within expected bounds, so malformed data can push the program into states its author never anticipated. Attackers probe these gaps to trigger crashes, bypass logic, or feed tainted values into more dangerous operations downstream. Remediating it well means validating and normalising every input at the boundary against a strict allow-list — not merely filtering known-bad values.

Recommended fix Moderate confidence

Firmware version specified in the November 2024 Qualcomm Security Bulletin (specific version numbers not provided in source material)

  1. Check the November 2024 Qualcomm Security Bulletin at https://docs.qualcomm.com/product/publicresources/securitybulletin/november-2024-bulletin.html for the specific fixed firmware versions applicable to your product model
  2. Identify your exact firmware version from the affected products list (Wcn3660b, Wcn3620, Wcd9340, Snapdragon X75, Snapdragon X72, Snapdragon 429, Sdm429w, or Qfw7124)
  3. Obtain the patched firmware version specified in the bulletin for your product
  4. Update the firmware to the patched version following standard Qualcomm firmware update procedures
  5. Verify the firmware update was successful and the version matches the fixed release
Caveat Firmware updates carry risk; ensure proper backup and follow vendor update procedures to avoid device bricking
