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
P30 smartphones with versions earlier than ELLE-AL00B 9.1.0.193(C00E190R2P1) have an insufficient verification vulnerability. The system does not verify certain parameters sufficiently, an attacker should connect to the phone and gain high privilege to launch the attack, successful exploit could cause malicious code execution.

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

Insufficient parameter verification in Huawei P30 smartphones (versions before ELLE-AL00B 9.1.0.193) allows authenticated attackers with high privilege to execute malicious code by connecting to the device and exploiting unchecked parameters.

MitigationUpdate P30 devices to firmware version ELLE-AL00B 9.1.0.193(C00E190R2P1) or later to remediate the insufficient verification vulnerability.

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 the device model
    Check if the target device is a Huawei P30 smartphone. This can be done by checking the device settings under 'Settings' > 'About Phone' > 'Model' or by examining the device packaging or system information.
    Affected if Device is not a Huawei P30 (the vulnerability only affects this specific model)
  2. Retrieve the firmware version
    Navigate to 'Settings' > 'About Phone' > 'Version' on the Huawei P30 device to display the current firmware build number. Alternatively, use the command 'AT^VERSION=' or check the build.prop file at /system/build.prop for the 'ro.build.display.id' or 'ro.sw.version' property.
    Affected if Unable to retrieve a firmware version from the device
  3. Compare firmware version against affected range
    Examine the firmware version string obtained from the previous step. The affected version range is any version before 'elle-al00b_9.1.0.193(c00e190r2p1)'. Compare your version string numerically and alphanumerically against this threshold.
    Affected if Firmware version is lower than elle-al00b_9.1.0.193 (for example, 9.1.0.150, 9.0.0.200, etc.) - this indicates the device is vulnerable
  4. Verify high-privilege access capability
    The vulnerability requires an authenticated attacker with high privilege to connect to the device and exploit unchecked parameters. Check if the device has debugging enabled (Settings > Developer Options > USB debugging) or if there are any exposed services accepting remote connections that could allow authenticated access.
    Affected if Device has USB debugging enabled or exposed network services that could allow an authenticated high-privilege attacker to connect and exploit unchecked parameters

The device is affected if it is a Huawei P30 running firmware version lower than elle-al00b_9.1.0.193(c00e190r2p1) and has the potential for an authenticated high-privilege attacker to connect and exploit unchecked parameters.
