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. Confirm NVIDIA hardware is present
    Check the device's system-on-chip (SoC) information via Settings > About Phone > Hardware info, or by running 'getprop ro.hardware' or 'cat /proc/cpuinfo' to verify the processor is NVIDIA-based
    Affected if The device does not contain an NVIDIA chipset (Tegra), then this vulnerability does not apply
  2. Verify Android version is 8.1 or earlier
    Navigate to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if Android version is 9.0 or higher (the affected range is only <= 8.1)
  3. Check the security patch level
    Navigate to Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch' via ADB shell
    Affected if The security patch level date is earlier than 2018-05-05 (the fix was released on that date)

A device is affected only if it has an NVIDIA SoC, runs Android 8.1 or earlier, AND has a security patch level before May 5, 2018.
