CVE-2015-9026
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 all Android releases from CAF using the Linux kernel, an untrusted pointer dereference vulnerability exists in WideVine DRM.
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 · low confidenceAn untrusted pointer dereference vulnerability exists in WideVine DRM within Android releases from CAF using the Linux kernel. The vulnerability allows a local attacker to potentially dereference an invalid pointer, leading to denial of service or potentially arbitrary code execution due to improper validation of pointer values before dereferencing.

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.
-
Verify WideVine DRM is present on the deviceCheck the device for WideVine DRM licensing: on Android, go to Settings > About Phone > WideVine DRM level (or use DRM Info apps from Play Store), or run 'getprop ro.widevine.drm.level' via ADBAffected if WideVine DRM is present and enabled on the device
-
Confirm the Android versionCheck the Android OS version in Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if The device runs any Android version (this CVE affects all versions according to the affected products list)
-
Check the security patch levelLook in Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch' via ADBAffected if The Security Patch Level is earlier than the June 2016 Android security bulletin (the patch for this CVE was released in the June 2016 bulletin)
-
Verify if this is a CAF-based Android buildCheck the build fingerprint or vendor: run 'getprop ro.build.fingerprint' or 'getprop ro.product.name' via ADB - CAF builds typically contain 'caf' or vendor-specific identifiers in the fingerprintAffected if The device uses a CAF (Code Aurora Forum) kernel or vendor-specific Android build with WideVine DRM enabled
A device is affected if it has WideVine DRM enabled and is running an Android version with a security patch level earlier than the June 2016 Android security bulletin.

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 security patches released through the Android monthly security bulletin for the affected CAF Android releases. As this is a kernel-adjacent DRM component, patching requires updating the system image with the latest vendor-specific security updates.
