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
The 'Find Phone' function in some Huawei smart phones with software earlier than Duke-L09C10B186 versions, earlier than Duke-L09C432B187 versions, earlier than Duke-L09C636B186 versions has an authentication bypass vulnerability. Due to improper authentication realization in the 'Find Phone' function. An attacker may exploit the vulnerability to bypass the 'Find Phone' function in order to use the phone normally.

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 · high confidence

The 'Find Phone' function in certain Huawei smartphones (Duke-L09 variants) contains an authentication bypass vulnerability due to improper authentication implementation. An attacker can exploit this to bypass the Find Phone function and use the phone normally, effectively circumventing security controls intended to protect a lost or stolen device.

MitigationUpdate affected Huawei smartphones to versions later than Duke-L09C10B186, Duke-L09C432B187, or Duke-L09C636B186 respectively to receive the vendor patch addressing the authentication flaw.

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 device model
    Check if the device is a Huawei smartphone, specifically the Duke-L09 or Duke-L09 variant (such as Duke-L09C, Duke-L09C432, Duke-L09C636). This can be done via Settings > About Phone > Model Number, or by checking the device packaging/label.
    Affected if Device is a Huawei Duke-L09 variant
  2. Check installed firmware version
    Navigate to Settings > About Phone > Build Number or use *#*#2846579#*#* to access engineering menu to view firmware version. Compare the version string against the three affected version thresholds: duke-l09c10b186, duke-l09c432b187, and duke-l09c636b186.
    Affected if Firmware version is lower than any of the three thresholds ( duke-l09c10b186, duke-l09c432b187, or duke-l09c636b186 )
  3. Verify Find Phone feature status
    Navigate to Settings > Find Phone (or Settings > Security > Find Phone) to check if the feature is enabled. The authentication bypass only affects devices where Find Phone has been configured and activated.
    Affected if Find Phone function is enabled and configured on the device

A user is affected if they own a Huawei Duke-L09 variant running firmware version lower than duke-l09c10b186, duke-l09c432b187, or duke-l09c636b186 AND have the Find Phone feature enabled.
