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 Bastet driver of Honor 9 Huawei smart phones with software of versions earlier than Stanford-AL10C00B175 has 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; the APP can send a specific parameter to the driver of the smart phone, causing 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 Bastet driver of Honor 9 smartphones. A malicious application with root privileges can send specially crafted parameters to the driver, bypassing validation checks and triggering the overflow, leading to arbitrary code execution in kernel context.

MitigationUpdate Honor 9 firmware to Stanford-AL10C00B175 or later version which contains the patched Bastet driver with proper parameter validation.

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 Honor 9 device model
    Check device model number in Settings > About Phone > Model Number. Confirm it is Honor 9 (model variants may include stanford-al10, stanford-al20, etc.)
    Affected if Device is not an Honor 9 smartphone - this vulnerability only affects Honor 9 models
  2. Check firmware version
    Navigate to Settings > About Phone > Version. Look for the build number or firmware version string (may appear as 'stanford-al10c00xxx' or similar)
    Affected if Firmware version begins with stanford-al10c00b175 or higher - versions starting with stanford-al10c00b175 or later are patched. Versions lower than stanford-al10c00b175 are affected
  3. Verify Bastet driver presence
    Use a terminal app with root access to check /dev or /sys for bastet driver entries, or run 'lsmod | grep bastet' if the driver is loadable as a kernel module
    Affected if Bastet driver is present and loaded - the vulnerability exists in this driver; if the driver is not present, the attack surface may not exist
  4. Check for root privilege exposure
    Verify if any untrusted applications have been granted superuser/root privileges. Check in Settings > Apps > superuser or using a root checker utility
    Affected if Untrusted or unknown applications have root/superuser access - a malicious root application is required to exploit this vulnerability

You are affected if you own an Honor 9 with firmware version below stanford-al10c00b175 and the Bastet driver is present on your device.
