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
A remote code execution vulnerability in the Qualcomm crypto driver could enable a remote attacker to execute arbitrary code within the context of the kernel. This issue is rated as Critical due to the possibility of remote code execution in the context of the kernel. Product: Android. Versions: N/A. Android ID: A-32652894. References: QC-CR#1077457.

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 remote code execution vulnerability in the Qualcomm crypto driver allows an attacker to execute arbitrary code in the kernel context. This is a critical flaw as it provides the attacker with the highest privilege level on the affected device, bypassing all userland security boundaries.

MitigationApply the appropriate Android security patch level (either the January 2017 Pixel/Nexus security patch or the carrier/OEM equivalent) which contains the fix for this Qualcomm crypto driver vulnerability.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 > Android version, or run 'getprop ro.build.version.release' via ADB
    Affected if Version is 6.0.1 or earlier (6.0, 5.1, 5.0, etc.)
  2. Identify chipset manufacturer
    Check device specifications for Qualcomm Snapdragon processor, or run 'getprop ro.hardware' or 'getprop ro.board.platform' via ADB
    Affected if Device uses a Qualcomm Snapdragon chipset (the vulnerable driver is specific to Qualcomm hardware)
  3. Verify crypto driver presence
    Check for the presence of the Qualcomm crypto driver module. On affected devices, this is typically a kernel module. Run 'ls /system/lib/modules/' or check /proc/modules via ADB to look for crypto-related modules from Qualcomm
    Affected if A Qualcomm crypto driver module is loaded or present on the device

The device is affected if it runs Android 6.0.1 or earlier on Qualcomm Snapdragon hardware with the vulnerable crypto driver present.

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.

dbcve · scoped
Upgrade available Upgrade to a release after 6.0.1
Interim mitigation

Apply the appropriate Android security patch level (either the January 2017 Pixel/Nexus security patch or the carrier/OEM equivalent) which contains the fix for this Qualcomm crypto driver vulnerability.

Recommended fix Moderate confidence

Android 7.0 or later with December 2016 security update or later

  1. Check for system updates on the affected Android device by going to Settings > About Phone > System Updates
  2. Ensure the device receives the December 2016 Android Security Patch Level or later
  3. If the device cannot receive updates, consider migrating to a device that supports newer Android versions with ongoing security support
  4. Verify the security patch level by going to Settings > About Phone > Android security patch level
Caveat Devices running Android 6.0.1 may not receive further updates; some devices may be end-of-life and require hardware replacement
