CVE-2016-5230
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 · uneditedHuawei Mate8 NXT-AL before NXT-AL10C00B182, NXT-CL before NXT-CL00C92B182, NXT-DL before NXT-DL00C17B182, and NXT-TL before NXT-TL00C01B182 allows attackers to bypass permission checks and control partial module functions via a crafted app.
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 confidenceThis is a privilege escalation vulnerability in Huawei Mate8 Android smartphones where a crafted malicious application can bypass standard Android permission checks, allowing unauthorized control of certain system module functions. The vulnerability affects multiple firmware variants (NXT-AL, NXT-CL, NXT-DL, NXT-TL) before specific version thresholds.

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 modelCheck Settings > About Phone > Model Number, or run 'adb shell getprop ro.product.model'Affected if Model is not Huawei Mate 8 (device model may appear as Huawei Mate8, HUAWEI NXT-AL10, or similar NXT variants)
-
Determine firmware variantCheck Settings > About Phone > Build Number, or run 'adb shell getprop ro.build.display.id' to identify if variant is NXT-AL, NXT-CL, NXT-DL, or NXT-TLAffected if Firmware variant is one of NXT-AL, NXT-CL, NXT-DL, or NXT-TL (any Mate8 variant)
-
Extract full build numberCheck Settings > About Phone > Build Number, or run 'adb shell getprop ro.build.version.emui' to get the EMUI version and 'adb shell getprop ro.build.version.incremental' for the full build stringAffected if Build number is earlier than: NXT-AL10C00B182, NXT-CL00C92B182, NXT-DL00C17B182, or NXT-TL00C01B182 (or build number cannot be determined)
A user is affected if they have a Huawei Mate 8 with firmware variant NXT-AL, NXT-CL, NXT-DL, or NXT-TL running a build version earlier than the patched thresholds listed.

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 vendor-provided firmware updates (NXT-AL10C00B182 or later, NXT-CL00C92B182 or later, NXT-DL00C17B182 or later, NXT-TL00C01B182 or later) to patch the permission bypass. Avoid installing applications from untrusted sources.
