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

This is a privilege escalation and denial-of-service vulnerability in Huawei Mate 8, Mate S, and P8 phones affecting the graphic and camera subsystems. Attackers who already possess graphic or Camera privilege can exploit this flaw to crash the system or escalate their privileges to higher levels. The vulnerability exists in specific software versions prior to the B386/B368/B366 builds depending on the model and variant.

MitigationApply the vendor-supplied firmware updates (NXT-AL10C00B386 and later for Mate 8, CRR-CL00C92B368 and later for Mate S, GRA-TL00C01B366 and later for P8) to address this vulnerability.

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 the phone model
    Check the device settings or physical device label to confirm it is a Huawei Mate 8, Mate S, or P8
    Affected if The device is not one of these three models, the CVE does not apply
  2. Check the firmware version
    Navigate to Settings > About Phone > Version on the device, or use ADB command: adb shell getprop ro.build.version.emui
    Affected if The firmware version cannot be determined or is not visible
  3. Compare version to fixed build for Mate 8
    If the device is Mate 8, verify if the version ends with B386 or later (e.g., B386, B387, B400)
    Affected if Version is earlier than B386 (e.g., B380, B360, B320)
  4. Compare version to fixed build for Mate S
    If the device is Mate S, verify if the version ends with B368 or later (e.g., B368, B370, B380)
    Affected if Version is earlier than B368 (e.g., B360, B350, B320)
  5. Compare version to fixed build for P8
    If the device is P8, verify if the version ends with B366 or later (e.g., B366, B370, B380)
    Affected if Version is earlier than B366 (e.g., B360, B350, B320)

A user is affected if they own a Mate 8, Mate S, or P8 device running firmware versions earlier than B386, B368, or B366 respectively.
