CVE-2017-8212
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 · uneditedThe driver of honor 5C,honor 6x Huawei smart phones with software of versions earlier than NEM-AL10C00B356, versions earlier than Berlin-L21HNC432B360 have a buffer overflow vulnerability due to the lack of parameter validation. An attacker tricks a user into installing a malicious APP which has the root privilege of the Android system, the APP can send a specific parameter to the driver of the smart phone, causing a system reboot or arbitrary code execution.
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 confidenceBuffer overflow vulnerability in the device driver of Huawei Honor 5C and Honor 6X smartphones due to missing parameter validation. A malicious application with root privileges can send a specific parameter to the driver, triggering the overflow and causing system reboot or arbitrary code execution.

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 device model and firmware versionGo to Settings > About Phone on the Huawei Honor device and locate the 'Build number' or 'Firmware version' field. For Honor 5C, note the NEM-AL10 build; for Honor 6X, note the Berlin-L21 build.Affected if Unable to retrieve firmware version from device settings
-
Check Honor 5C firmware version against thresholdCompare the installed NEM-AL10 build number to the vulnerable threshold. The affected version range is any build lower than NEM-AL10C00B356.Affected if Build number is NEM-AL10xx where the numeric portion is less than 00b356 (for example, NEM-AL10c00b300)
-
Check Honor 6X firmware version against thresholdCompare the installed Berlin-L21 build number to the vulnerable threshold. The affected version range is any build lower than Berlin-L21HNC432B360.Affected if Build number is Berlin-L21xx where the version code is lexicographically or numerically less than HNC432b360
The device is affected if it is an Honor 5C running firmware below NEM-AL10C00B356 or an Honor 6X running firmware below Berlin-L21HNC432B360.

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 dataUpdate device firmware to versions NEM-AL10C00B356 or later (Honor 5C) and Berlin-L21HNC432B360 or later (Honor 6X). Only install applications from trusted sources to reduce risk of malicious app installation.
