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 confidence

Integer overflow vulnerability in keymaster 4 security subsystem where multiplication of a large numcerts value with the size of a keymaster structure can overflow during memory allocation, resulting in allocation of an undersized buffer and subsequent memory corruption. This exists in multiple Snapdragon chipset generations across mobile, IoT, automotive, and infrastructure products.

MitigationApply Qualcomm firmware/security patch updates for affected chipsets; devices should be updated to latest vendor-provided Android security patch level. Consider disabling keymaster certificate storage features if not needed as a defense-in-depth measure.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify device chipset model
    Check the device specifications or system information to determine the Qualcomm chipset model (e.g., via Settings > About Phone, or via 'getprop' command on Android: 'getprop ro.hardware' or 'getprop ro.board.platform')
    Affected if The chipset matches Apq8009, Apq8017, Apq8053, Apq8096au, Apq8098, Kamorta, Mdm9150, or Mdm9205 - all firmware versions of these chipsets are affected
  2. Check Android security patch level
    On Android devices, check Settings > About Phone > Security Patch Level, or run 'getprop ro.build.version.security_patch'
    Affected if The security patch level is earlier than the date when this CVE was patched by the vendor (typically May 2019 or later for affected Qualcomm devices)
  3. Verify keymaster module is in use
    Check if the keymaster Trusted Execution Environment module is active by examining keymaster HAL services: run 'dumpsys keymaster' or check '/vendor/etc/init/[email protected]' process
    Affected if Keymaster 4.0 or keymaster HAL service is running - the vulnerability exists in the keymaster 4 security subsystem
  4. Confirm firmware version details
    Check firmware/baseband version via 'getprop ro.build.fingerprint' or 'getprop gsm.version.baseband' - this reveals the specific Qualcomm firmware build
    Affected if The firmware is from before the May 2019 security update cycle for the affected chipset

A user is affected if their device uses one of the listed Qualcomm chipsets (Apq8009, Apq8017, Apq8053, Apq8096au, Apq8098, Kamorta, Mdm9150, Mdm9205) and has not received the vendor security patch that addresses CVE-2019-10615.
