CVE-2017-18170
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 · uneditedImproper input validation in Bluetooth Controller function can lead to possible memory corruption in Snapdragon Mobile in version QCA9379, SD 210/SD 212/SD 205, SD 410/12, SD 425, SD 427, SD 430, SD 435, SD 450, SD 615/16/SD 415, SD 625, SD 650/52, SD 820, SD 835, SD 845, SD 850, SDM630, SDM636, SDM660, SDM710, Snapdragon_High_Med_2016.
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 confidenceImproper input validation in the Bluetooth Controller function allows an attacker within Bluetooth range to send malformed input that can cause memory corruption. This is a firmware-level vulnerability affecting Qualcomm Snapdragon mobile processors.

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 Qualcomm Snapdragon modelCheck your device specifications, system settings 'About phone', or manufacturer website to determine the exact Snapdragon processor model number (e.g., SD 210, SD 410, etc.)Affected if The device uses any of the following models: Qca9379, SD 210, SD 212, SD 205, SD 410, SD 412, SD 425, or SD 427
-
Verify Bluetooth is enabledCheck device Bluetooth settings or system status bar to confirm Bluetooth is turned onAffected if Bluetooth is actively enabled on the device (the vulnerability requires Bluetooth to be in use for an attack to succeed)
-
Check the Bluetooth firmware versionOn Android devices, access Settings > About phone > Bluetooth version or use a Bluetooth info app to retrieve the Bluetooth controller firmware versionAffected if The Bluetooth firmware version cannot be determined, is older than vendor patches, or matches unpatched firmware builds for the affected Snapdragon models
-
Check for vendor security updatesCheck Settings > About phone > Software update or Security patch level to see the last installed security update date and versionAffected if The device has not received security updates that address CVE-2017-18170, or the Security patch level predates the vendor fix date (typically early 2017)
A user is affected if their mobile device contains an affected Qualcomm Snapdragon chipset (Qca9379, SD 210, SD 212, SD 205, SD 410, SD 412, SD 425, or SD 427), has Bluetooth enabled, and is running firmware without the CVE-2017-18170 security patch.

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-supplied firmware updates for affected Snapdragon processors. Users should ensure their mobile devices receive regular security updates from device manufacturers.
