CVE-2016-8455
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. Android ID: A-32219121. References: B-RB#106311.
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 confidenceLocal privilege escalation vulnerability in the Broadcom Wi-Fi driver for Android Kernel-3.10. A malicious application that has already compromised a privileged process can exploit this flaw to execute arbitrary code within kernel context, achieving full kernel-level code execution.

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 kernel versionRun `uname -r` or check `/proc/version` to determine the exact kernel versionAffected if The kernel version is exactly 3.10 (or contains 3.10 in the version string)
-
Confirm Broadcom Wi-Fi driver presenceCheck for loaded Wi-Fi driver modules using `lsmod | grep -i brcm` or look for Broadcom firmware files in `/lib/firmware/brcm/`Affected if Broadcom Wi-Fi driver (brcmfmac, brcm, or similar brcm* modules) is loaded or present on the system
-
Verify driver is actively usedCheck if the Wi-Fi interface is enabled or running `iwconfig` or check network interfaces for wlan0 presenceAffected if Wi-Fi is enabled and using a Broadcom driver interface (wlan0 with Broadcom chipset)
-
Check Android security patch levelOn Android devices, check Settings > About Phone > Security Patch Level or run `getprop ro.build.version.security_patch`Affected if The security patch level is earlier than November 2016 or the property is empty/unavailable
Environment is affected if running kernel 3.10 with an active Broadcom Wi-Fi driver and the device lacks the November 2016 or later Android Security Patch Level.

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 security patch from Google/Android (A-32219121) which updates the Broadcom Wi-Fi driver. This is included in the November 2016 Android Security Patch Level or later.
