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
Huawei P9 smartphones with the versions before EVA-AL10C00B399SP02 have an information disclosure vulnerability. The software does not properly protect certain resource which can be accessed by multithreading. An attacker tricks the user who has root privilege to install a crafted application, successful exploit could result in kernel information disclosure.

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 · moderate confidence

A race condition vulnerability exists in Huawei P9 smartphones where certain kernel resources are not properly protected against concurrent multithreaded access. An attacker with root privileges can install a crafted application that exploits this race condition to read kernel memory and disclose sensitive information.

MitigationUpdate the device to firmware version EVA-AL10C00B399SP02 or later, which contains proper synchronization primitives to protect the vulnerable kernel resources from concurrent access.

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 is Huawei P9
    Check device model number in Settings > About Phone, or run 'getprop ro.product.model' via ADB shell
    Affected if Model is not Huawei P9 (e.g., P9 Lite, P9 Plus)
  2. Identify firmware version
    Check the build number in Settings > About Phone > Build Number, or run 'getprop ro.build.display.id' via ADB shell
    Affected if Unable to retrieve firmware version information
  3. Compare against affected version
    Compare your build number to 'eva-al10c00b399sp02'. Versions below this threshold (such as eva-al10c00bXXX) are vulnerable
    Affected if Build number is lexicographically or numerically lower than eva-al10c00b399sp02
  4. Verify kernel-level access
    Confirm you have root access by running 'su' in ADB shell or checking for root management apps. The vulnerability requires root privileges to exploit
    Affected if Device is not rooted and you cannot execute privileged commands

If your Huawei P9 firmware version is lower than eva-al10c00b399sp02 and you have root access, your device is affected by this race condition vulnerability.
