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 P30 smartphone with versions earlier than 10.1.0.135(C00E135R2P11) have an improper input verification vulnerability. An attribution in a module is not set correctly and some verification is lacked. Attackers with local access can exploit this vulnerability by injecting malicious fragment. This may lead to user 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 · high confidence

Improper input verification vulnerability in Huawei P30 smartphones. An attribute in a module is incorrectly set without proper validation, allowing a local attacker to inject malicious fragments and potentially leak user information.

MitigationUpdate Huawei P30 devices to version 10.1.0.135(C00E135R2P11) or later. For enterprise environments, deploy firmware updates through mobile device management (MDM) systems and verify complete fleet coverage.

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. Verify device model is Huawei P30
    Go to Settings > About Phone > Model Number and confirm the device is specifically Huawei P30
    Affected if Device model is not Huawei P30 (other models are not affected by this specific CVE)
  2. Locate firmware version information
    Navigate to Settings > About Phone on the Huawei P30 device
    Affected if Unable to access firmware version information
  3. Identify the build number and version
    In Settings > About Phone, record the Build Number and Software Version displayed
    Affected if Version information cannot be retrieved from the device
  4. Compare against affected version
    Compare the installed firmware version to 10.1.0.135(C00E135R2P11) - check if the version is lower than this build
    Affected if Firmware version is < 10.1.0.135(C00E135R2P11) - the device is affected by the vulnerability

A Huawei P30 is affected if its firmware version is lower than 10.1.0.135(C00E135R2P11).
