CVE-2019-14042
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 · moderate confidenceOut-of-bounds read vulnerability in the fingerprint application where requested data is assigned to a local buffer without proper length validation, potentially allowing an attacker to read sensitive memory contents beyond buffer boundaries.

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 device chipsetCheck /proc/cpuinfo or system settings > About Phone > Model/Hardware information for the processor/chipset nameAffected if The chipset is one of: Kamorta, Mdm9205, Nicobar, Qcs404, Qcs405, Qcs605, Rennell, or Sa415m
-
Verify fingerprint hardware is presentCheck if the device has a fingerprint sensor via Settings > Security > Fingerprint, or check /dev/fingerprint or /sys/class/fingerprint entriesAffected if Fingerprint sensor hardware and software stack are present on the device
-
Check fingerprint daemon/process versionLocate the fingerprint service process (commonly android.hardware.fingerprint or fingerprintd) and query its version via ps or /proc/<pid>/version if accessibleAffected if The fingerprint service version cannot be determined or is from an unpatched firmware build
-
Determine firmware version from buildCheck Settings > About Phone > Build Number or /system/build.prop for the firmware/build version stringAffected if The firmware is an unpatched build from before the CVE disclosure date (November 2019)
The device is affected if it uses any of the listed Qualcomm chipsets (Kamorta, Mdm9205, Nicobar, Qcs404, Qcs405, Qcs605, Rennell, Sa415m) and has an active fingerprint sensor, since the vulnerability exists in all firmware versions of these chipsets.

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/security patches for affected Snapdragon chipsets; contact device OEMs for patch availability and deployment schedules.
