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 Huawei smartphones ALP-AL00B 8.0.0.118D(C00), ALP-TL00B 8.0.0.118D(C01), BLA-AL00B 8.0.0.118D(C00), BLA-L09C 8.0.0.127(C432), 8.0.0.128(C432), 8.0.0.137(C432), BLA-L29C 8.0.0.129(C432), 8.0.0.137(C432) have an authentication bypass vulnerability. When the attacker obtains the user's smartphone, the vulnerability can be used to replace the start-up program so that the attacker can obtain the information in the smartphone and achieve the purpose of controlling the smartphone.

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

This is an authentication bypass vulnerability in specific Huawei smartphone models (ALP-AL00B, ALP-TL00B, BLA-AL00B, BLA-L09C, BLA-L29C) running firmware versions 8.0.0.118D through 8.0.0.137. An attacker with physical access to the device can replace the startup program, bypassing authentication to gain access to stored data and achieve full device control.

MitigationApply vendor-supplied firmware updates from Huawei to patch this vulnerability. Since the attack requires physical access, maintain physical control of devices and avoid leaving them unattended in public spaces.

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 number
    Go to Settings > About Phone on the device and check the model number field
    Affected if The model number matches ALP-AL00B, ALP-TL00B, BLA-AL00B, BLA-L09C, or BLA-L29C
  2. Check firmware version
    Go to Settings > About Phone > Build Number and identify the exact firmware version string
    Affected if The firmware version is 8.0.0.118D (c00 or c01), 8.0.0.127 (c432), 8.0.0.128 (c432), or 8.0.0.137 (c432)
  3. Verify build number matches
    Compare the full build number shown in Settings > About Phone against the specific build identifiers listed in the affected versions
    Affected if The build number exactly matches one of the vulnerable builds: c00, c01, or c432 for the versions listed

The device is affected if it is one of the five model numbers listed and runs one of the specific firmware versions 8.0.0.118D through 8.0.0.137 with the matching build identifiers.
