CVE-2019-14135
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.

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 confidenceInteger overflow vulnerability in WLAN firmware when parsing nonstandard NAN (Neighbor Awareness Networking) Information Element messages. The overflow allows heap or stack buffer overflow, potentially enabling remote code execution or denial of service via malformed WiFi frames.

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 chipset modelCheck the device specifications or system information to determine if the chipset matches any of the following: Apq8009, Apq8017, Apq8053, Apq8096au, Ipq8074, Mdm9206, Mdm9207c, or Mdm9607Affected if The chipset is one of the listed affected models
-
Verify the WLAN firmware versionQuery the WLAN firmware version through the device's diagnostic interface, firmware information utility, or manufacturer documentationAffected if The device uses one of the affected chipsets and the firmware is present (all versions are affected according to the advisory)
-
Confirm NAN functionality is enabledCheck the WiFi configuration settings or wireless driver parameters to determine if Neighbor Awareness Networking (NAN) is turned on. This may be accessible through wlan driver debug interfaces, config files, or wireless management toolsAffected if NAN is actively enabled and the device uses an affected chipset
-
Check for unexpected WiFi behaviorMonitor wireless interface logs, kernel messages, or firmware crash dumps for signs of heap or stack corruption related to WiFi frame handling, or anomalous device resets after receiving WiFi framesAffected if The device exhibits unexplained WiFi crashes or memory corruption events and uses an affected chipset with NAN enabled
A user is affected if their device uses any of the listed Qualcomm chipsets (Apq8009, Apq8017, Apq8053, Apq8096au, Ipq8074, Mdm9206, Mdm9207c, Mdm9607) and has NAN functionality enabled, since all firmware versions for these chipsets contain the vulnerability.

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 firmware patches from device manufacturers (Qualcomm Snapdragon). As interim mitigation, disable NAN functionality on affected devices if supported, or restrict WiFi exposure to trusted networks.
