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
Information disclosure while capturing logs as eSE debug messages are logged.

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

An information disclosure vulnerability exists where eSE (embedded Secure Element) debug messages are being captured in logs, potentially exposing sensitive information that should not be visible.

MitigationDisable or remove eSE debug message logging in production environments, or ensure logs containing such messages are properly sanitized/redacted before storage or review.

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 the Qualcomm firmware in use
    Check system documentation, firmware version, or device specifications to determine if the system uses Fastconnect 6900, Fastconnect 7800, Qca9367, Qca9377, Qcs8550, Sa8530p, Sa8540p, or Sa9000p firmware.
    Affected if The system uses any of the listed Qualcomm firmware products.
  2. Locate eSE debug logging configuration
    Search system configuration files, firmware settings, or diagnostic menus for options related to eSE (embedded Secure Element) debug logging, trace logging, or verbose logging. Look for settings like 'eSE debug', 'SE debug', 'secure element logging', or similar.
    Affected if eSE debug logging is enabled or configurable in the system.
  3. Examine system log files for eSE messages
    Review system log files (such as debug logs, system logs, kernel logs, or vendor-specific diagnostic logs) for entries containing keywords like 'eSE', 'secure element', 'SE', 'embedded Secure Element', or related debug labels.
    Affected if Log files contain any eSE or Secure Element related messages.
  4. Inspect eSE log content for sensitive data
    Analyze any eSE-related log entries found for the presence of sensitive information such as cryptographic keys, tokens, authentication data, PINs, or other secure element data that should not be exposed in plain text.
    Affected if Log entries contain sensitive information from the embedded Secure Element in plain text.

The user is affected if their system uses any of the listed Qualcomm firmware products and eSE debug messages with sensitive data are present in their logs.
