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 smart phones with versions earlier than ELLE-AL00B 9.1.0.193(C00E190R2P1) have an integer overflow vulnerability due to insufficient check on specific parameters. An attacker tricks the user into installing a malicious application, obtains the root permission and constructs specific parameters to the camera program to exploit this vulnerability. Successful exploit could cause the program to break down or allow for arbitrary 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

Integer overflow vulnerability in the camera program of Huawei P30 smartphones running firmware versions earlier than ELLE-AL00B 9.1.0.193(C00E190R2P1). The vulnerability stems from insufficient validation of specific parameters, allowing an attacker who has already obtained root privileges to send crafted input to the camera service, triggering the overflow and potentially causing denial of service or arbitrary code execution.

MitigationApply vendor firmware update ELLE-AL00B 9.1.0.193(C00E190R2P1) or later to patched camera component. Restrict installation of applications from untrusted sources and revoke unnecessary root privileges to limit attack surface.

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. Confirm device model is Huawei P30
    Go to Settings > About Phone > Model Number, or run 'getprop ro.product.model' via ADB/shell
    Affected if Model is not Huawei P30 (the vulnerability only affects this specific model)
  2. Check firmware version/build number
    Go to Settings > About Phone > Version > Build Number, or run 'getprop ro.build.version.emui' and 'getprop ro.build.display.id' via ADB/shell
    Affected if Build number is earlier than ELLE-AL00B 9.1.0.193(C00E190R2P1) or cannot be determined to be that version or later
  3. Verify camera service is accessible
    Attempt to open the camera application, or run 'dumpsys camera' via ADB/shell to confirm camera service is active
    Affected if Camera service is running and accessible (the overflow triggers when crafted input is sent to this service)
  4. Confirm root privilege status
    Check if the device has been rooted (e.g., presence of SuperSU, Magisk, or 'su' binary in common paths, or 'id' command showing uid=0)
    Affected if Root privileges are present on the device - the advisory states the attacker must already have root to exploit this vulnerability

User is affected if they are on a Huawei P30 with firmware earlier than ELLE-AL00B 9.1.0.193(C00E190R2P1) and the device has been rooted, since the attacker requires root privileges to trigger the integer overflow in the camera service.
