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, NVIDIA Tegra bootloader contains a vulnerability in nvtboot where the Trusted OS image is improperly authenticated, which may lead to code execution, denial of service, escalation of privileges, and information disclosure, code execution, denial of service, or escalation of privileges

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 · high confidence

This is a bootloader vulnerability in NVIDIA Tegra processors (used in Shield TV devices). The nvtboot component fails to properly authenticate the Trusted OS image before execution, allowing a privileged attacker to potentially execute arbitrary code, cause denial of service, escalate privileges, or disclose sensitive information.

MitigationUpdate NVIDIA Shield TV Experience to v8.0 or later, which contains the patched bootloader with proper Trusted OS image authentication.

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. Identify NVIDIA Shield TV device
    Confirm the device is an NVIDIA Shield TV (model numbers SHIELD, SHIELD Pro, or SHIELD Tablet) which uses NVIDIA Tegra processors
    Affected if Device is not a NVIDIA Shield TV or non-Tegra device - this CVE does not apply
  2. Check Shield Experience version
    Navigate to Settings > About > Shield Experience Version on the device, or use ADB command: adb shell getprop ro.build.version.full
    Affected if The displayed version is below 8.0 (e.g., 7.x, 6.x, etc.)
  3. Verify nvtboot bootloader component
    This requires reading the bootloader version via device firmware inspection or manufacturer documentation - the vulnerability exists in nvtboot if running an unpatched bootloader
    Affected if Bootloader was released before the v8.0 patch (this is implicit if Experience version is < 8.0)

A user is affected if they are running an NVIDIA Shield TV device with Shield Experience version lower than 8.0, as this indicates the vulnerable nvtboot bootloader that lacks proper Trusted OS image authentication.
