CVE-2017-0567
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 Broadcom Wi-Fi 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-32125310. References: B-RB#112575.
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 confidenceA local privilege escalation vulnerability in the Broadcom Wi-Fi driver for Android allows a malicious application that has already compromised a privileged process to execute arbitrary code within kernel context. The flaw affects Android devices running Kernel-3.10 and Kernel-3.18.

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 Android kernel versionRun 'uname -r' or check /proc/version to retrieve the running kernel versionAffected if The kernel version is exactly 3.10.x or 3.18.x
-
Confirm Broadcom Wi-Fi hardware is presentCheck the device specifications or run 'ls -la /sys/class/net' to see Wi-Fi interface details; Broadcom Wi-Fi devices typically show as wlan0Affected if The device uses Broadcom Wi-Fi hardware and the kernel is 3.10 or 3.18
-
Verify the Wi-Fi driver module is loadedRun 'lsmod' or check /proc/modules to see if a Broadcom Wi-Fi driver module (such as bcmdhd or similar) is currently loadedAffected if A Broadcom Wi-Fi driver module is loaded on an affected kernel version
-
Check the Android security patch levelGo to Settings > About Phone > Build Number or run 'getprop ro.build.version.security_patch' to see the installed security patch levelAffected if The security patch level is earlier than March 2017
The device is affected if it runs Android with kernel 3.10 or 3.18, uses Broadcom Wi-Fi hardware, and has a security patch level earlier than March 2017.

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 Android security patch level for March 2017 or later, which includes the Broadcom Wi-Fi driver update. Organizations should ensure mobile devices receive regular security updates from device OEMs.
