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
The GPU driver in Huawei P7 phones with software P7-L00 before P7-L00C17B851, P7-L05 before P7-L05C00B851, and P7-L09 before P7-L09C92B851 allows local users to read or write to arbitrary kernel memory locations and consequently cause a denial of service (system crash) or gain privileges via a crafted application.

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

Local privilege escalation vulnerability in the GPU driver of Huawei P7 phones (P7-L00, P7-L05, P7-L09) allows a malicious local application to read/write arbitrary kernel memory locations, leading to system crash or root-level privilege escalation.

MitigationApply vendor firmware updates: upgrade P7-L00 to P7-L00C17B851 or later, P7-L05 to P7-L05C00B851 or later, and P7-L09 to P7-L09C92B851 or later.

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
    Go to Settings > About Phone > Model Number (or use *#*#2846579#*#* on dialer for test menu) and verify if the model is P7-L00, P7-L05, or P7-L09
    Affected if The model number matches P7-L00, P7-L05, or P7-L09
  2. Check the firmware version
    Navigate to Settings > About Phone > Version Number and note the build number; for P7-L00 look for C17B851, for P7-L05 look for C00B851, for P7-L09 look for C92B851
    Affected if The device is a P7 model with a firmware version earlier than the fixed build numbers (P7-L00 < C17B851, P7-L05 < C00B851, P7-L09 < C92B851) or if the version cannot be determined
  3. Verify GPU driver presence
    Check if the device has a Mali or other GPU driver by examining /system/lib/modules/ or using a system information app to view kernel modules
    Affected if The device has a Mali or PowerVR GPU driver loaded, which is the typical GPU for the Kirin processor in P7 phones
  4. Confirm root access status
    Check if the device has been rooted by looking for superuser apps (SuperSU, Magisk) in the app drawer or by using a root checker app
    Affected if The device already has root access, as the vulnerability allows privilege escalation to root

A user is affected if they own a Huawei P7-L00, P7-L05, or P7-L09 running firmware versions earlier than the fixed builds (C17B851, C00B851, C92B851 respectively), particularly if the GPU driver is present and the device has not been patched.
