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, all versions prior to 8.2.2, contains a vulnerability in the NVHost function, which may lead to abnormal reboot due to a null pointer reference, causing data loss.

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

NVIDIA SHIELD TV devices before version 8.2.2 contain a null pointer reference vulnerability in the NVHost function. When triggered, this causes an abnormal system reboot and potential data loss.

MitigationUpdate NVIDIA SHIELD TV firmware to version 8.2.2 or later to patch the null pointer vulnerability in the NVHost function.

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 NVIDIA SHIELD TV firmware version
    Navigate to Settings > About on the SHIELD TV device and locate the 'Build' number to determine the Shield Experience version
    Affected if The Shield Experience version is lower than 8.2.2
  2. Check Nvidia Linux For Tegra version
    Run 'cat /proc/version' or 'cat /etc/nv_tegra_release' on the Tegra device to identify the L4T release version
    Affected if The L4T version is lower than r32.5
  3. Identify NVHost module usage
    Check if the NVHost kernel module is loaded or present by running 'lsmod | grep nvhost' or examining /proc/modules on the device
    Affected if The NVHost module is actively in use on an affected version

The environment is affected if the installed Shield Experience version is below 8.2.2 or the Linux For Tegra version is below r32.5, and the NVHost function is being utilized.
