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
NULL pointer access vulnerability in the clock module Impact: Successful exploitation of this vulnerability will affect availability.

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

A NULL pointer dereference vulnerability in the clock module allows an attacker to cause a denial of service by triggering the NULL pointer access, likely resulting in a crash or system instability.

MitigationImplement proper NULL pointer validation in the clock module before dereferencing pointers, and ensure all clock-related structures are properly initialized before use.

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 installed Huawei OS version
    On the Huawei device, go to Settings > About Phone > Version. Alternatively, use 'getprop ro.build.version.emui' for EMUI or 'getprop ro.build.version.harmonyos' for HarmonyOS via ADB shell.
    Affected if The version displayed matches exactly: 12.0.0, 13.0.0, or 14.0.0 for EMUI; or 2.0.0, 2.1.0, 3.0.0, 4.0.0, or 4.2.0 for HarmonyOS
  2. Confirm the clock module is accessible
    Verify that clock-related functionality is available on the device. Check if any clock, time, or alarm applications are installed and operational.
    Affected if Clock applications or system clock services are running on the device
  3. Check for clock module access patterns
    Monitor system logs (logcat) for clock-related operations or crashes. Look for entries containing 'clock', 'clk', or similar references during normal device operation.
    Affected if The device experiences unexpected crashes, reboots, or system instability when clock features are accessed, or NULL pointer dereference errors appear in logs

A user is affected if their Huawei device runs EMUI 12.0.0, 13.0.0, or 14.0.0, or HarmonyOS 2.0.0, 2.1.0, 3.0.0, 4.0.0, or 4.2.0, and they observe crashes or instability when interacting with clock-related functionality.
