CVE-2017-6293
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 · uneditedIn Android before the 2018-05-05 security patch level, NVIDIA Tegra X1 TZ contains a vulnerability in Widevine TA where the software writes data past the end, or before the beginning, of the intended buffer, which may lead to escalation of Privileges. This issue is rated as high. Android: A-69377364. Reference: N-CVE-2017-6293.
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 confidenceA buffer overflow vulnerability exists in the Widevine Trusted Application (TA) running on NVIDIA Tegra X1 processors within TrustZone (TZ). The software writes data beyond the boundaries of an allocated buffer, allowing an attacker to corrupt memory and escalate privileges. This affects Android devices with the affected Tegra X1 chipset before the May 2018 security patch level.

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 the SoC processorCheck /proc/cpuinfo or use 'getprop ro.hardware' to identify the system-on-chip. Look for 'Tegra' or 'T210' which indicates Tegra X1.Affected if The device uses NVIDIA Tegra X1 (T210) processor.
-
Check the Android security patch levelRun 'getprop ro.build.version.security_patch' or check Settings > About Phone > Android security patch level.Affected if Patch level is earlier than 2018-05-05 (e.g., 2018-04-05, 2018-03-05, or earlier).
-
Verify Widevine DRM is presentCheck for the presence of /vendor/lib/hw/widevine.*.so or /system/lib/libwidevine*.so, or run 'dumpsys media.drm' to list installed DRM providers.Affected if Widevine DRM components exist on the device (required for the vulnerable TA to be present).
The device is affected if it uses an NVIDIA Tegra X1 processor, has a security patch level before May 2018, and contains Widevine DRM components.

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 Android security patch level 2018-05-05 or later, which contains the fix (A-69377364) for this vulnerability. Organizations should identify and update all affected devices running NVIDIA Tegra X1 hardware.
