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 confidence

This is an elevation of privilege vulnerability in the Broadcom Wi-Fi driver for Android. The vulnerability exists in the driver code that operates at the kernel level, allowing a malicious application to potentially gain elevated system privileges through the Wi-Fi subsystem. The specific vulnerability mechanism is not detailed in the available description.

MitigationApply the Android security patch level for June 2017 or later, which includes the fix for this Broadcom Wi-Fi driver vulnerability. Users should ensure their devices receive regular security updates from their device manufacturers.

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. Check Android version
    Go to Settings > About phone (or About device) > Android version. Verify the version is exactly 7.1.2.
    Affected if Android version is 7.1.2
  2. Confirm Broadcom Wi-Fi chipset is present
    Check device specifications or examine kernel module information via terminal: 'ls -la /system/lib/modules/' or check 'getprop ro.wifi.driver' if available. Broadcom Wi-Fi drivers typically appear as files containing 'bcmdhd', 'brcm', or 'broadcom' in the module or driver directory.
    Affected if Device uses a Broadcom Wi-Fi chipset and driver
  3. Verify Wi-Fi driver kernel module
    Run 'lsmod' in a terminal to list loaded kernel modules. Look for modules named 'bcmdhd', 'brcmfmac', 'brcmutil', or similar Broadcom identifiers.
    Affected if Broadcom Wi-Fi kernel module is loaded and the Android version is 7.1.2

A device is affected if it runs Android 7.1.2 and contains a Broadcom Wi-Fi driver/chipset, since this specific version is the only affected Android release listed.
