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 confidence

This is a privilege escalation vulnerability in Huawei Mate 8, Mate S, and P8 smartphones affecting the graphics/camera subsystem. Attackers with existing graphic or Camera privilege can exploit this to crash the system or escalate to higher privileges.

MitigationApply the vendor firmware update from Huawei that addresses this vulnerability - update to versions after NXT-AL10C00B386 (Mate 8), CRR-CL00C92B368 (Mate S), or GRA-TL00C01B366 (P8).

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 your device model
    Go to Settings > About Phone on your Huawei smartphone and confirm the exact model name (Mate 8, Mate S, or P8)
    Affected if The device model is Huawei Mate 8, Mate S, or P8 - only these models are affected by this vulnerability
  2. Check your current firmware version
    In Settings > About Phone, locate the 'Version' or 'Build number' field. Compare this to the fixed versions: NXT-AL10C00B386 for Mate 8, CRR-CL00C92B368 for Mate S, GRA-TL00C01B366 for P8
    Affected if The firmware version is earlier than the fixed versions listed, or shows 'all versions' with no update available
  3. Verify if Camera or graphics privileges are accessible
    Review installed applications and their permissions. Check if any application has Camera permission or access to the graphics subsystem (this varies by Android version and custom Huawei settings)
    Affected if Applications with Camera or graphics subsystem access exist on the device - this is the prerequisite condition for exploitation
  4. Confirm the graphics/camera subsystem is active
    Check if the camera application can be launched and the graphics rendering subsystem is operational on your device
    Affected if The camera and graphics subsystem is functional and accessible to applications on the device

Your device is affected if it is a Mate 8, Mate S, or P8 running firmware versions earlier than the fixed builds, and applications with camera or graphics privileges can be accessed on the device.
