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 · unedited
The graphics driver in Huawei P8 smartphones with software GRA-TL00 before GRA-TL00C01B230, GRA-CL00 before GRA-CL00C92B230, GRA-CL10 before GRA-CL10C92B230, GRA-UL00 before GRA-UL00C00B230, and GRA-UL10 before GRA-UL10C00B230 allows attackers to cause a denial of service (system crash) via a crafted application, aka a "semaphore deadlock issue."

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

The graphics driver in Huawei P8 smartphones (models GRA-TL00, GRA-CL00, GRA-CL10, GRA-UL00, GRA-UL10) contains a semaphore deadlock vulnerability. A crafted malicious application can trigger this condition in the graphics driver, causing a system crash and denial of service.

MitigationApply the vendor-supplied firmware updates from Huawei that address the graphics driver semaphore deadlock issue. Users should update their devices to the specified patched versions (GRA-TL00C01B230, GRA-CL00C92B230, GRA-CL10C92B230, GRA-UL00C00B230, or GRA-UL10C00B230) or later.

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 model number
    Check the device model in Settings > About Phone > Model Number
    Affected if model is GRA-TL00, GRA-CL00, GRA-CL10, GRA-UL00, or GRA-UL10
  2. Check firmware version
    Check the firmware build number in Settings > About Phone > Version or Build Number
    Affected if firmware version is gra-cl00c92b220, gra-cl10c92b220, gra-tl00c01b220, gra-ul00c00b220, or gra-ul10c00b220

The device is affected if it is one of the listed Huawei P8 models running one of the specific vulnerable firmware versions.
