CVE-2014-9800
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 · uneditedInteger overflow in lib/heap/heap.c in the Qualcomm components in Android before 2016-07-05 on Nexus 5 and 7 (2013) devices allows attackers to gain privileges via a crafted application, aka Android internal bug 28822150 and Qualcomm internal bug CR692478.
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 confidenceInteger overflow in lib/heap/heap.c within Qualcomm components for Android allows a crafted application to overflow heap allocation size parameters, potentially causing memory corruption and privilege escalation on affected Nexus 5 and 7 (2013) devices running Android versions prior to the July 2016 security patch.

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 if the device is a Nexus 5 or Nexus 7 (2013) by viewing the device settings under About Phone or About Tablet, or by running 'getprop ro.product.model' via ADBAffected if Device model is Nexus 5 or Nexus 7 (2013)
-
Check Android versionNavigate to Settings > About Phone/Tablet > Android version, or run 'getprop ro.build.version.release' via ADBAffected if Android version is 6.0.1 or lower
-
Verify security patch levelCheck Settings > About Phone/Tablet > Security patch level, or run 'getprop ro.build.version.security_patch' via ADBAffected if Security patch level is earlier than July 2016 or not displayed
-
Confirm Qualcomm component presenceThis vulnerability exists in Qualcomm heap implementation; confirm the device uses a Qualcomm chipset by checking 'getprop ro.hardware' or 'getprop ro.board.platform'Affected if Device uses a Qualcomm chipset (most Nexus devices do)
-
Check if device is still receiving updatesAttempt to check for system updates in Settings > About Phone/Tablet > System updates, or verify with your carrier/OEM if updates are availableAffected if Device cannot receive the July 2016 or later security update
A user is affected if they are running Android 6.0.1 or earlier on a Nexus 5 or Nexus 7 (2013) device with a security patch level before July 2016.

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 the July 2016 Android security update or later to affected Nexus 5 and 7 (2013) devices to incorporate the fix for this heap integer overflow vulnerability in Qualcomm components.
