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 CameraISP driver of some Huawei smart phones with software of versions earlier than Prague-AL00AC00B205,versions earlier than Prague-AL00BC00B205,versions earlier than Prague-AL00CC00B205,versions earlier than Prague-TL00AC01B205,versions earlier than Prague-TL10AC01B205 has a buffer overflow vulnerability due to the lack of parameter validation. An attacker tricks a user into installing a malicious APP, the APP can send a specific parameter to the CameraISP driver of the smart phone, causing system reboot.

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 CameraISP driver of certain Huawei smartphones (Prague series) due to lack of parameter validation. A malicious application can send a specific crafted parameter to the driver, triggering the overflow and causing system reboot.

MitigationUpdate Huawei smartphone software to version Prague-AL00AC00B205 or later (and equivalent for other variants). Users should avoid installing untrusted applications to prevent exploitation.

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
    Check if the device is a Huawei Prague series phone by going to Settings > About Phone > Model Number and verify it matches one of: Al00a, Al00b, Al00c, Tl00a, or Tl10a
    Affected if Device model is not a Prague series variant listed in the affected products
  2. Check firmware version
    Go to Settings > About Phone > Version and locate the build number. Compare it against the threshold for your specific model: Al00a must be < prague-al00ac00b205, Al00b must be < prague-al00bc00b205, Al00c must be < prague-al00cc00b205, Tl00a must be < prague-tl00ac01b205, Tl10a must be < prague-tl10ac01b205
    Affected if Firmware version is lower than the specified threshold for your specific Prague model

The device is affected if it is a Huawei Prague series model (Al00a/b/c, Tl00a, Tl10a) running firmware version below the listed threshold for that variant, and the CameraISP driver is present on the device.
