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
Honor 6X smartphones with software versions earlier than BLN-AL10C00B357 and versions earlier than BLN-AL20C00B357 have an information leak vulnerability due to improper file permission configuration. An attacker tricks a user into installing a malicious application on the smart phone, and the application can get the file that keep the cipher text of the SIM card PIN.

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

Honor 6X smartphones with versions earlier than BLN-AL10C00B357 and BLN-AL20C00B357 contain an information disclosure vulnerability where improper file permission configuration allows a malicious application installed on the device to access a file containing the encrypted SIM card PIN cipher text.

MitigationUpdate Honor 6X firmware to version BLN-AL10C00B357 or later (for BLN-AL10 model) and BLN-AL20C00B357 or later (for BLN-AL20 model) to remediate the improper file permission configuration.

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 Honor 6X model number
    Go to Settings > About Phone and note the model number - look for BLN-AL10 or BLN-AL20
    Affected if Your model is BLN-AL10 or BLN-AL20 (other models are not affected by this CVE)
  2. Check your current firmware version
    Go to Settings > About Phone > Version and record the build number shown
    Affected if The firmware version is visible on the screen - you need to compare this to the affected ranges
  3. Compare BLN-AL10 firmware to affected range
    If your model is BLN-AL10, compare your build number against BLN-AL10C00B357 - check if it is earlier than (less than) this version
    Affected if Your version is earlier than BLN-AL10C00B357 (e.g., BLN-AL10C00B340 or similar)
  4. Compare BLN-AL20 firmware to affected range
    If your model is BLN-AL20, compare your build number against BLN-AL20C00B357 - check if it is earlier than (less than) this version
    Affected if Your version is earlier than BLN-AL20C00B357 (e.g., BLN-AL20C00B340 or similar)
  5. Confirm the file permission vulnerability context
    This CVE relates to improper file permissions on a system file that stores encrypted SIM PIN data - the vulnerability exists if your firmware version is below the thresholds regardless of other factors
    Affected if Your firmware version is below the indicated threshold for your specific model

You are affected if you have an Honor 6X (BLN-AL10 or BLN-AL20) with firmware version earlier than BLN-AL10C00B357 (for BLN-AL10) or BLN-AL20C00B357 (for BLN-AL20).
