CVE-2021-1068
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 NVDEC component, in which an attacker can read from or write to a memory location that is outside the intended boundary of the buffer, 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 confidenceOut-of-bounds memory access vulnerability in the NVDEC (NVIDIA video decoder) component on NVIDIA SHIELD TV devices prior to firmware version 8.2.2. The vulnerability allows a local attacker to read from or write to memory locations outside the intended buffer boundaries, potentially leading to denial of service or privilege escalation.

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.
-
Confirm device is NVIDIA SHIELD TVCheck the device model in Settings > About > Device name or look for the SHIELD TV hardware unitAffected if Device is not an NVIDIA SHIELD TV (this CVE affects only SHIELD TV devices)
-
Check Shield Experience firmware versionNavigate to Settings > About > Version on the NVIDIA SHIELD TV and note the displayed version numberAffected if Version number is lower than 8.2.2 (for example, 8.2.1, 8.1.0, etc.)
-
Verify NVDEC component presenceThe NVDEC (NVIDIA Video Decoder) is a built-in component of the SHIELD TV firmware and is present by default on all affected versions; no manual check needed as it is always accessible to local attackers on vulnerable firmwareAffected if Device runs vulnerable firmware (any version below 8.2.2) and NVDEC is present (which it always is on SHIELD TV)
The device is affected if it is an NVIDIA SHIELD TV running Shield Experience firmware version 8.2.1 or lower, since the out-of-bounds memory access flaw exists in the NVDEC component on those versions.
