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 Camera driver in Huawei Honor 4C smartphones with software CHM-UL00C00 before CHM-UL00C00B564, CHM-TL00C01 before CHM-TL00C01B564, and CHM-TL00C00 before CHM-TL00HC00B564 allows attackers to cause a denial of service (system crash) or gain privileges via a crafted application, a different vulnerability than CVE-2016-6180, CVE-2016-6181, CVE-2016-6183, and CVE-2016-6184.

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

A vulnerability in the camera driver of Huawei Honor 4C smartphones (models CHM-UL00C00, CHM-TL00C01, CHM-TL00C00) allows a malicious application to trigger either a system crash (denial of service) or escalate privileges, likely due to improper input validation or memory handling in the driver code that operates with elevated privileges.

MitigationUsers should update their device firmware to the patched versions (CHM-UL00C00B564, CHM-TL00C01B564, or CHM-TL00HC00B564 and above) to remediate this vulnerability. No application-level workaround exists as this is a driver-level flaw.

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. Verify device model is affected Honor 4C variant
    Check the device model number in Settings > About Phone. Confirm it matches one of: CHM-UL00C00, CHM-TL00C01, or CHM-TL00C00 (or TL00HC00 variant).
    Affected if Device model is any of the three listed Honor 4C variants.
  2. Check installed firmware version
    Navigate to Settings > About Phone > Version. Compare the build number or firmware version string against the affected list: chm-tl00c01_b535, chm-tl00c01b556, chm-tl00hc00_b535, chm-tl00hc00b556, chm-ul00c00b535, or chm-ul00c00b556.
    Affected if Firmware version exactly matches any of the six listed vulnerable versions.
  3. Confirm camera driver is accessible
    The vulnerability exists in the camera driver component. Verify the camera driver module exists on the device (typically in /system/lib/modules or /vendor/lib/hw) by using a file explorer with root access or ADB shell to list the camera-related kernel module or library.
    Affected if Camera driver module is present and the device supports camera functionality.
  4. Inspect system logs for camera-related crashes
    Use ADB logcat or a log viewer app to search for camera driver crash logs (look for keywords like 'camera', 'driver', 'crash', 'kernel panic', or 'system server'). Check if recent crashes align with camera driver activity.
    Affected if Camera driver crashes appear in logs without an obvious benign cause.

User is affected if the device is a Huawei Honor 4C (CHM-UL00C00, CHM-TL00C01, or CHM-TL00C00/TL00HC00 variant) AND the firmware version exactly matches one of the six listed vulnerable builds.
