CVE-2017-6276
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 mediaserver contains a vulnerability where it is possible a use after free malfunction can occur due to an incorrect bounds check which could enable unauthorized code execution and possibly lead to elevation of privileges. This issue is rated as high. Product: Android. Version: N/A. Android: A-63802421. References: N-CVE-2017-6276.
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 mediaserver on Android contains a use-after-free vulnerability caused by an incorrect bounds check. This memory safety flaw can be exploited to achieve unauthorized code execution, potentially with elevated privileges, by corrupting memory through the freed pointer.

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 NVIDIA chipset presenceCheck if the device uses an NVIDIA processor by reviewing the hardware specifications or checking /proc/cpuinfo for NVIDIA-related identifiersAffected if The device runs an NVIDIA SoC (e.g., Tegra series) and contains the NVIDIA mediaserver component
-
Locate NVIDIA mediaserver binaryCheck for the existence of the mediaserver binary in system partitions, typically found at /system/bin/mediaserver or within /vendor/lib/hw/ on NVIDIA-based Android devicesAffected if The NVIDIA mediaserver binary is present on the device
-
Verify Android security patch levelCheck the system property ro.build.version.security_patch or Settings > About Phone > Android security patch level. This indicates whether the device has received the fix for A-63802421Affected if The installed security patch level is earlier than the patch containing the fix for A-63802421 (the vulnerability remains unpatched)
-
Check mediaserver component versionIf available, run 'getprop | grep mediaserver' or inspect the mediaserver binary version through debugging tools to compare against the vulnerable version rangeAffected if The mediaserver version corresponds to a build before the fix was applied and the security patch is unapplied
A user is affected if the device contains an NVIDIA mediaserver component and lacks the Android security patch that addresses A-63802421, leaving the bounds check vulnerability unmitigated.

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 appropriate Android security patch level containing the fix for A-63802421, or obtain and integrate the NVIDIA-provided patch for the mediaserver component that corrects the bounds check logic.
