CVE-2016-8480
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 · uneditedAn elevation of privilege vulnerability in the Qualcomm Secure Execution Environment Communicator driver could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as High because it first requires compromising a privileged process. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID: A-31804432. References: QC-CR#1086186.
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 confidenceElevation of privilege vulnerability in the Qualcomm Secure Execution Environment Communicator (SEEC) driver allows a local malicious application to execute arbitrary code within the kernel context. The vulnerability requires the attacker to first compromise a privileged process before exploiting this flaw to gain kernel-level access.

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.
-
Check kernel versionRun 'uname -r' or 'cat /proc/version' to identify the running kernel versionAffected if The kernel version is 3.10.x or 3.18.x (exact match to the affected versions)
-
Identify SEEC driver presenceCheck for the SEEC driver module by running 'ls /dev/seec' or searching kernel config with 'grep -i seec /boot/config-$(uname -r)'Affected if The SEEC driver is present and loaded on the system
-
Verify Android security patch levelOn Android devices, run 'getprop ro.build.version.security_patch' to check the installed security patch levelAffected if The security patch level is earlier than the fix for A-31804462 (pre-January 2017 security update) on Android 7.1.1 or earlier
A system is affected if it runs Linux kernel 3.10 or 3.18 with the Qualcomm SEEC driver loaded, or is an Android device on version 7.1.1 or below without the January 2017 security update that includes the fix for A-31804462.

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 the vendor-specific security patch (QC-CR#1086186) via Android monthly security update. Ensure devices receive the Android security patch level that includes the fix for A-31804432.
