CVE-2019-5700
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 · uneditedNVIDIA Shield TV Experience prior to v8.0.1, NVIDIA Tegra software contains a vulnerability in the bootloader, where it does not validate the fields of the boot image, which may lead to code execution, denial of service, escalation of privileges, and 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 · high confidenceThe NVIDIA Shield TV/Tegra bootloader does not validate fields in the boot image, allowing a malicious or crafted boot image to be processed without integrity checks. This could enable an attacker to execute arbitrary code at the bootloader level, cause denial of service, escalate privileges to the most privileged execution context, or leak sensitive information from the boot process.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify device modelConfirm the device is an NVIDIA Shield TV or Tegra-based device by checking the device model number or packagingAffected if Device is an NVIDIA Shield TV or Tegra device of any model
-
Check Shield Experience versionNavigate to Settings > About > Version on the NVIDIA Shield TV device, or use the command 'getprop ro.build.version.sdk' or check system settings for the Shield Experience versionAffected if Shield Experience version is below 8.0.1 (e.g., 7.x, 8.0.0)
-
Verify bootloader versionAccess the device bootloader/fastboot mode and run 'fastboot devices' followed by 'fastboot getvar version-bootloader' to retrieve the bootloader version if accessibleAffected if Bootloader version cannot be verified or is older than the version shipped with 8.0.1
-
Confirm if device received updateCheck if the device has ever received the 8.0.1 or later firmware update by reviewing system update history in Settings > System > Software Update > Update historyAffected if Device has never received Shield Experience 8.0.1 or later update
If the device is an NVIDIA Shield TV or Tegra unit running Shield Experience version prior to 8.0.1, the bootloader is vulnerable to unauthenticated boot image field validation bypass.

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.
From vendor data8.0.1
Apply the vendor firmware update (v8.0.1 or later) to all affected NVIDIA Shield TV and Tegra devices to ensure the bootloader includes proper boot image field validation.
