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
Some Honor products are affected by type confusion vulnerability, successful exploitation could cause information leak.

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

Type confusion vulnerability in Honor products allows attackers to cause an information leak. The vulnerability is network-exploitable with low complexity and no authentication required, but impact is limited to information disclosure rather than full system compromise.

MitigationApply vendor-provided security updates from Honor for affected products. Until a patch is available, minimize network exposure of vulnerable devices and monitor for indicators of compromise.

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. Confirm Honor device model
    Check the device settings under 'Settings' > 'About Phone' > 'Device Name' to confirm it is an Honor or Hihonor device
    Affected if Device is not an Honor or Hihonor product - this CVE does not apply to other vendors
  2. Check Magic OS version
    Navigate to 'Settings' > 'About Phone' > 'Magic OS version' or 'Software version' to view the installed OS version number
    Affected if Magic OS version is not displayed or cannot be determined - version must be explicitly identified for this check
  3. Compare version against affected range
    Compare the displayed version number to 7.0.0.129. The affected range is any version less than 7.0.0.129 (for example: 7.0.0.128, 6.x.x.x, etc.)
    Affected if Installed version is 7.0.0.129 or higher - the device is not in the affected version range
  4. Verify network exposure (optional context)
    Check if the device has open network services or is directly accessible from untrusted networks - this vulnerability is network-exploitable
    Affected if Device is directly exposed to untrusted networks without firewall protection

The device is affected if it is an Honor/Hihonor product running Magic OS version lower than 7.0.0.129, as this is the specific version range identified as vulnerable to the type confusion flaw enabling information disclosure.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 7.0.0.129 or later
Fixed in 7.0.0.129
Interim mitigation

Apply vendor-provided security updates from Honor for affected products. Until a patch is available, minimize network exposure of vulnerable devices and monitor for indicators of compromise.

Recommended fix Moderate confidence

Magic OS 7.0.0.129 or later

  1. Check current Magic OS version on the Honor device
  2. Upgrade Magic OS to version 7.0.0.129 or later via system settings or Honor's official update mechanism
  3. After upgrade, verify the version has been successfully applied
