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
In cplog service, there is a possible out of bounds write due to a missing bounds check. This could lead to local denial of service with no additional execution privileges needed.

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

A missing bounds check in the cplog service allows an out of bounds write to occur, leading to local denial of service. The vulnerability stems from insufficient validation of buffer or array indices before write operations.

MitigationImplement proper bounds checking on all array and buffer write operations in the cplog service to prevent out of bounds access. Consider performing input validation and adding runtime checks around memory operations.

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 Android version
    Check the device settings under Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if The installed Android version is exactly 13.0, 14.0, or 15.0
  2. Locate the cplog service
    Run 'dumpsys | grep -i cplog' or check for cplog-related processes via 'ps -A | grep cplog' in ADB shell
    Affected if The cplog service is present and running on the device
  3. Verify cplog service status
    Run 'service list' or check 'dumpsys activity service' output to confirm cplog is registered as an active system service
    Affected if The cplog service appears in the active service list and is not disabled

A device is affected if it runs Android version 13.0, 14.0, or 15.0 and has the cplog service enabled, since the bounds check vulnerability exists in that specific service on those exact versions.
