CVE-2021-1067
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, all versions prior to 8.2.2, contains a vulnerability in the implementation of the RPMB command status, in which an attacker can write to the Write Protect Configuration Block, which may lead to 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 confidenceNVIDIA SHIELD TV devices prior to version 8.2.2 contain a vulnerability in the RPMB (Replay Protected Memory Block) command status implementation. The flaw allows an attacker to write to the Write Protect Configuration Block, which may cause denial of service or enable privilege escalation. RPMB is a secure storage partition used for sensitive data, making unauthorized write access particularly dangerous.

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 NVIDIA SHIELD TV deviceCheck the device model by navigating to Settings > About > Device name or model number on the SHIELD TVAffected if The device is not an NVIDIA SHIELD TV or SHIELD Pro model
-
Check Shield Experience firmware versionNavigate to Settings > About > Version number on the NVIDIA SHIELD TV. The version displayed is the Shield Experience versionAffected if The displayed version is below 8.2.2 (for example, 8.2.1, 8.2.0, or earlier)
-
Verify RPMB partition accessThis vulnerability affects the RPMB (Replay Protected Memory Block) secure storage partition. On affected versions, the RPMB is accessible through low-level storage access tools or debugging interfaces that allow RPMB command executionAffected if The device runs a vulnerable firmware version AND has RPMB functionality accessible (which is present by default on SHIELD TV devices)
A user is affected if they have an NVIDIA SHIELD TV or SHIELD Pro device running Shield Experience firmware version lower than 8.2.2, as the RPMB vulnerability exists in those versions.

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 data8.2.2
Update NVIDIA SHIELD TV devices to firmware version 8.2.2 or later. Organizations should inventory affected devices and apply the patch through the device's built-in update mechanism or OTA deployment tools.
