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
Huawei ALP-L09 smart phones with versions earlier than ALP-L09 8.0.0.150(C432) have an insufficient input validation vulnerability due to lack of parameter check. An attacker tricks the user who has root privilege to install a crafted application, the application may modify the specific data to exploit the vulnerability. Successful exploit could allow the attacker to execute arbitrary code.

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

Insufficient input validation in Huawei ALP-L09 smartphones prior to version ALP-L09 8.0.0.150(C432) allows a malicious application, installed by tricking a privileged (root) user, to modify specific data through unchecked parameters, leading to arbitrary code execution.

MitigationUpdate affected devices to firmware version ALP-L09 8.0.0.150(C432) or later. Additionally, enforce policies preventing installation of untrusted applications on privileged devices.

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 ALP-L09 by viewing the device information in Settings > About Phone > Model Number
    Affected if Device model is Huawei ALP-L09 and not another variant
  2. Check firmware version
    Navigate to Settings > About Phone > Version to find the build number and compare it to 8.0.0.150(C432)
    Affected if Firmware version is lower than 8.0.0.150(C432)
  3. Check if untrusted apps can be installed
    Navigate to Settings > Security > Unknown Sources (or Settings > Apps > Install Unknown Apps) to see if installation from unknown sources is enabled
    Affected if Installation from unknown sources is allowed and a malicious application has been installed

The device is affected if it is a Huawei ALP-L09 running firmware version lower than 8.0.0.150(C432) and a malicious application was installed by tricking a privileged user.
