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
Path traversal vulnerability in the virtualization file module. Successful exploitation of this vulnerability may affect the confidentiality of the virtualization file module.

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 path traversal vulnerability exists in the virtualization file module, allowing attackers to use "../" sequences to access files outside the intended directory. This enables unauthorized read access to potentially sensitive files on the host system, impacting confidentiality.

MitigationImplement strict input validation and path canonicalization to sanitize file paths, ensuring ".." sequences cannot escape the intended directory. Apply proper file access controls and restrict the module to allowed directory boundaries.

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 HarmonyOS version
    Check the device version through Settings > About Device > Version, or run 'adb shell getprop ro.build.version.harmonyos' via Android Debug Bridge
    Affected if Version is exactly 5.0.1 or 5.0.2
  2. Verify virtualization file module presence
    Check system modules through Settings > System > Virtualization, or run 'adb shell vm -list' or 'ls /system/lib/modules/' to enumerate virtualization components
    Affected if Virtualization file module is present and enabled on the device
  3. Inspect file access permissions
    Review the virtualization module's file access configuration at /data/virtualization/ or through the device security settings panel
    Affected if The module has unrestricted file system access or lacks proper directory boundary controls
  4. Examine system logs for traversal patterns
    Run 'adb shell logcat | grep -E "\.\." | grep -i virtual' to search for suspicious path traversal attempts in recent system logs
    Affected if Logs show evidence of '../' patterns in file access requests within the virtualization module

A device is affected if it runs HarmonyOS version 5.0.1 or 5.0.2 AND has the virtualization file module enabled, as this module contains the path traversal vulnerability that allows directory escape via '../' sequences.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement strict input validation and path canonicalization to sanitize file paths, ensuring ".." sequences cannot escape the intended directory. Apply proper file access controls and restrict the module to allowed directory boundaries.

Recommended fix Moderate confidence

HarmonyOS 5.0.3 or later (verify latest available version via Huawei security advisories)

  1. Check Huawei's official security advisory page at consumer.huawei.com for the latest HarmonyOS security patch information
  2. Identify the latest HarmonyOS version available for your device (versions after 5.0.2 may contain the fix)
  3. Update your HarmonyOS device to the latest available version through Settings > System > Software Update
  4. After updating, verify the virtualization file module is functioning correctly
  5. If OTA update is not available, contact Huawei customer support for patch availability
Caveat Standard OS update risks apply - ensure backup of important data before updating
