CVE-2015-9127
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 · uneditedIn Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile and Snapdragon Wear MSM8909W, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 615/16/SD 415, and SD 810, possible null pointer dereference occurs due to failure of memory allocation when a large value is passed for buffer allocation in the Playready App.
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 confidenceA null pointer dereference vulnerability exists in the Playready App on affected Qualcomm Snapdragon processors (MSM8909W, SD 210/212/205, SD 400, SD 410/12, SD 615/16/SD 415, SD 810). When a large value is passed for buffer allocation, memory allocation fails and returns NULL, which is then dereferenced, potentially allowing arbitrary code execution.

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 Snapdragon processor modelCheck the device specifications or system information to confirm the processor is one of: MSM8909W, SD 210, SD 212, SD 205, SD 400, SD 410, SD 412, or SD 615Affected if The processor model matches one of the listed affected Snapdragon variants
-
Check the baseband/MODEM firmware versionAccess the device diagnostics or use *#*#7265726F#*#* or similar code to view baseband version information, or check via Settings > About Phone > Baseband versionAffected if The firmware version cannot be determined or is present on an affected processor model (all versions are affected)
-
Verify Playready component is presentCheck device system files or installed packages for the presence of the Playready library or service (typically found in /system/lib/ or as part of media frameworks)Affected if The Playready component is installed and active on the device
-
Confirm Android security patch levelNavigate to Settings > About Phone > Android security patch level, or run 'getprop ro.build.version.security_patch' via ADBAffected if The patch level is earlier than 2018-04-05 or cannot be verified (all versions of the affected processors are vulnerable without the fix)
A user is affected if the device uses one of the listed Snapdragon processors (MSM8909W, SD 210/212/205, SD 400, SD 410/12, SD 615) and the Android security patch level is earlier than 2018-04-05.
