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
NVIDIA Shield TV Experience prior to v8.0, contains a vulnerability in the custom NVIDIA API used in the mount system service where user data could be overridden, which may lead to code execution, denial of service, or information disclosure.

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 vulnerability exists in the custom NVIDIA API within the mount system service on NVIDIA Shield TV devices running versions prior to 8.0. The flaw allows user data to be overridden, potentially enabling code execution, denial of service, or information disclosure. This represents a data injection/manipulation vulnerability in a privileged system service.

MitigationUpdate NVIDIA Shield TV Experience to version 8.0 or later, which contains the patched firmware addressing this vulnerability in the mount system service.

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 Shield TV device
    Check the device model through Settings > About > Device name or look for the Shield TV hardware
    Affected if The device is not an NVIDIA Shield TV unit
  2. Check Shield Experience version
    Navigate to Settings > About > Shield Experience version on the device, or check via adb shell: getprop ro.build.version.shield_experience
    Affected if Unable to retrieve the Shield Experience version
  3. Compare version to affected range
    Verify if the installed Shield Experience version is below 8.0 (for example, 7.x.x or earlier)
    Affected if Shield Experience version is 7.x.x or any version prior to 8.0
  4. Verify mount system service status
    Check if the mount system service is accessible or running: adb shell dumpsys mount (requires developer mode enabled)
    Affected if Mount system service is exposed to user-accessible APIs

A user is affected if their NVIDIA Shield TV runs Shield Experience version prior to 8.0, as this version range contains the vulnerable mount system service API.
