CVE-2015-8089
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 · uneditedThe 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 confidenceLocal 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelGo 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-L09Affected if The model number matches P7-L00, P7-L05, or P7-L09
-
Check the firmware versionNavigate 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 C92B851Affected 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
-
Verify GPU driver presenceCheck if the device has a Mali or other GPU driver by examining /system/lib/modules/ or using a system information app to view kernel modulesAffected if The device has a Mali or PowerVR GPU driver loaded, which is the typical GPU for the Kirin processor in P7 phones
-
Confirm root access statusCheck if the device has been rooted by looking for superuser apps (SuperSU, Magisk) in the app drawer or by using a root checker appAffected 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply 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.
