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

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 update from OEM containing the August 2019 Code Aurora security patch

  1. 1. Review the August 2019 Code Aurora Security Bulletin at https://www.codeaurora.org/security-bulletin/2019/08/05/august-2019-code-aurora-security-bulletin for the specific patch for CVE-2019-10538
  2. 2. Contact your device OEM/manufacturer to obtain firmware images containing the security fix
  3. 3. Apply the OEM-provided firmware update that includes the address range validation fix
  4. 4. Verify the patch has been applied by checking the firmware version or through OEM verification tools
Caveat Firmware updates carry risk of bricking device; ensure OEM provides validated update; some older devices may no longer receive updates
