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 · unedited
The MediaTek connectivity kernel driver in Android 6.0.1 before 2016-03-01 allows attackers to gain privileges via a crafted application that leverages conn_launcher access, aka internal bug 25873324.

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

A privilege escalation vulnerability in the MediaTek connectivity kernel driver for Android 6.0.1 allows a crafted local application to gain elevated privileges by improperly leveraging conn_launcher access, bypassing normal permission boundaries.

MitigationApply Android security patches released March 2016 or later, which contain the MediaTek driver fix. Organizations should inventory affected MediaTek-based devices and ensure they receive vendor security updates.

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. Verify Android version
    Check Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB
    Affected if Version is exactly 6.0.1
  2. Confirm MediaTek chipset
    Run 'getprop ro.hardware' or 'getprop ro.mediatek.platform' via ADB to identify the chipset manufacturer
    Affected if Device uses a MediaTek chipset and the MediaTek connectivity driver is present
  3. Check conn_launcher module
    Run 'lsmod | grep conn_launcher' or check /proc/modules via ADB shell to see if the conn_launcher kernel module exists
    Affected if The conn_launcher module is loaded and accessible to untrusted applications

Device is affected if running Android 6.0.1 on MediaTek hardware with the vulnerable conn_launcher driver present and exploitable by a local application.
