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 in diagnostic services due to absence of input validation

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 · low confidence

Memory corruption vulnerability exists in diagnostic services stemming from insufficient input validation. This could allow an attacker to corrupt memory through malicious input to diagnostic functions, potentially leading to code execution or denial of service.

MitigationImplement comprehensive input validation on all diagnostic service interfaces to ensure data bounds checking and sanitization before processing. Conduct thorough code review of diagnostic modules to identify and remediate all entry points lacking validation.

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 your Qualcomm firmware product
    Check the system information, firmware version, or device specifications to determine if the hardware uses one of the affected Qualcomm components: Aqt1000, Cologne, Fastconnect 6200, Fastconnect 6700, Fastconnect 6800, Fastconnect 6900, Fastconnect 7800, or Iqx5121 firmware.
    Affected if The system uses any of the listed Qualcomm firmware products.
  2. Locate diagnostic services
    Inspect the system for diagnostic service processes, modules, or daemons related to Qualcomm diagnostic functionality. Check for services with names containing 'diag', 'diagnostic', 'diagd', or similar identifiers.
    Affected if Diagnostic services related to the Qualcomm firmware are present on the system.
  3. Verify diagnostic service status
    Determine whether diagnostic services are actively enabled, running, or accessible. Check service status, startup configuration, or runtime flags that control diagnostic functionality.
    Affected if Diagnostic services are enabled or running on the affected firmware.
  4. Inspect diagnostic service configuration
    Review configuration files, registry entries, or service parameters that control diagnostic service behavior. Look for settings that enable or control input handling in diagnostic paths.
    Affected if Diagnostic services are configured with accessible input paths or exposed interfaces.

If your system contains any of the affected Qualcomm firmware products and diagnostic services are enabled, you are likely affected by this vulnerability.
