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 Wi-Fi module has an event notification vulnerability.Successful exploitation of this vulnerability may allow third-party applications to intercept event notifications and add information and result in elevation-of-privilege.

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

The Wi-Fi module in affected devices has a vulnerability in its event notification mechanism that allows untrusted third-party applications to intercept and potentially modify Wi-Fi event notifications. This improper access control enables an attacker to manipulate event data and escalate privileges.

MitigationApply vendor-provided security patches for the Wi-Fi module firmware. Until patches are available, restrict installation of untrusted third-party applications and monitor for suspicious Wi-Fi-related activity.

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 device OS and version
    Go to Settings > About Phone (or System > About Device) and record the displayed OS version and whether it shows EMUI, HarmonyOS, or Magic UI
    Affected if The version matches 10.1.0, 10.1.1, 11.0.0, or 12.0.0 for EMUI; 2.0 for HarmonyOS; or 3.1.0, 3.1.1, or 4.0.0 for Magic UI
  2. Confirm Wi-Fi functionality is enabled
    Verify that Wi-Fi is turned on in your device settings (Settings > Network & Internet > Wi-Fi or similar path depending on your OS version)
    Affected if Wi-Fi is actively enabled and used on the device
  3. Review third-party app permissions
    Check installed applications for those requesting Wi-Fi-related permissions (such as ACCESS_WIFI_STATE, CHANGE_WIFI_STATE, or Wi-Fi event listeners) by navigating to Settings > Apps > [select app] > Permissions
    Affected if Apps from unknown or untrusted sources have been granted Wi-Fi event or state permissions

Your device is affected if it runs one of the listed OS versions and has Wi-Fi enabled with potentially untrusted third-party apps installed that have Wi-Fi permissions.
