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 driver of honor 5C,honor 6x Huawei smart phones with software of versions earlier than NEM-AL10C00B356, versions earlier than Berlin-L21HNC432B360 have a buffer overflow vulnerability due to the lack of parameter validation. An attacker tricks a user into installing a malicious APP which has the root privilege of the Android system, the APP can send a specific parameter to the driver of the smart phone, causing a system reboot or arbitrary code execution.

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

Buffer overflow vulnerability in the driver for Honor 5C and Honor 6x smartphones due to lack of parameter validation. A malicious application with root privileges can send specific parameters to the device driver, causing buffer overflow that leads to system reboot or arbitrary code execution.

MitigationApply the vendor firmware update: upgrade to NEM-AL10C00B356 or later for Honor 5C, and Berlin-L21HNC432B360 or later for Honor 6x. Since exploitation requires root-level access, ensure devices are not compromised prior to patching.

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. Confirm device model
    Go to Settings > About Phone or use 'getprop ro.product.name' via ADB to verify the device is Honor 5C (NEM-AL10) or Honor 6x (Berlin)
    Affected if Device model is not Honor 5C or Honor 6x
  2. Check Honor 5C firmware version
    Go to Settings > About Phone > Version or use 'getprop ro.build.version.emui' via ADB. Compare the build number to nem-al10c00b356
    Affected if Firmware version is less than nem-al10c00b356 on Honor 5C
  3. Check Honor 6x firmware version
    Go to Settings > About Phone > Version or use 'getprop ro.build.version.emui' via ADB. Compare the build number to berlin-l21hnc432b360
    Affected if Firmware version is less than berlin-l21hnc432b360 on Honor 6x
  4. Verify driver module presence
    Check if the vulnerable device driver is loaded by examining /proc/modules or using 'lsmod' via ADB shell. The specific driver name would need to be identified from device drivers list
    Affected if Vulnerable driver module is present and loaded on the device

The device is affected if it is an Honor 5C with firmware below nem-al10c00b356 or an Honor 6x with firmware below berlin-l21hnc432b360, and the vulnerable driver is loaded.
