CVE-2018-6271
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 Tegra OpenMax driver (libnvomx) contains a vulnerability in which the software delivers extra data with the buffer and does not properly validated the extra data, which may lead to denial of service or escalation of privileges. Android ID: A-80198474.
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 confidenceNVIDIA Tegra OpenMax driver (libnvomx) contains a buffer validation vulnerability where extra data delivered with a buffer is not properly validated, potentially allowing 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.
-
Identify NVIDIA Tegra hardware presenceCheck /proc/cpuinfo for 'NVIDIA Tegra' or use 'getprop ro.hardware' to see the hardware identifierAffected if Device does not contain NVIDIA Tegra processor - not affected by this specific vulnerability
-
Locate the libnvomx librarySearch for libnvomx.so in system directories such as /system/lib/ or /vendor/lib/Affected if The libnvomx library is not present on the device - vulnerability does not apply
-
Verify OpenMax driver interface accessibilityCheck if the /dev/nvhost-ctrl or /dev/nvhost-vi interface nodes exist and are readable/writable by application processesAffected if OpenMax driver interface nodes are accessible to untrusted applications - attack surface is present
-
Check application permissions to OpenMax driverReview SELinux policy or file permissions on /dev/nv* device nodes to determine if third-party apps can access the driverAffected if Untrusted applications have permission to interact with the OpenMax driver - potential for exploitation exists
Device is affected if it contains NVIDIA Tegra hardware with the libnvomx library present and the OpenMax driver interface is accessible to untrusted applications.

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 dataApply the NVIDIA security patch for this vulnerability; until patched, minimize exposure by restricting untrusted applications' access to the OpenMax driver interface.
