CVE-2017-17327
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 smartphones with software of MHA-AL00AC00B125 have an improper resource management vulnerability. The software does not properly manage the resource when do device register operation. An attacker tricks the user who has root privilege to install a crafted application, successful exploit could cause certain service unavailable.
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 vulnerability in Huawei smartphones (MHA-AL00AC00B125) involves improper resource management during the device registration operation. An attacker with root privileges tricks the user into installing a crafted malicious application that exploits this resource management flaw, causing certain services to become unavailable (denial of service).

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.
-
Verify device firmware versionCheck the device system settings or use *#*#2846579#*#* service menu to confirm the exact firmware build number is mha-al00ac00b125Affected if The firmware version matches exactly mha-al00ac00b125
-
Confirm device model is MHA-AL00Verify the device model number in Settings > About Phone shows MHA-AL00 or MHA-AL00AAffected if The device model is Huawei MHA-AL00 series running the vulnerable firmware
-
Check for root privilege escalationUse a root checker application or verify if SU binary exists in /system/xbin/ or /system/bin/Affected if Root access is present on the device (prerequisite for the attack)
-
Review installed applications from untrusted sourcesInspect installed applications in Settings > Apps, looking for unfamiliar or recently installed applications from unknown sources outside the official app storeAffected if User has installed applications from untrusted or unknown sources
The device is affected only if it runs exactly firmware version mha-al00ac00b125 AND an attacker with root privileges has tricked the user into installing a malicious application.

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 dataRestrict root privilege escalation on devices and only install applications from trusted sources. If available, apply vendor-supplied firmware updates that address this resource management issue.
