CVE-2022-22258
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 · uneditedThe 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 confidenceThe 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify your device OS and versionGo to Settings > About Phone (or System > About Device) and record the displayed OS version and whether it shows EMUI, HarmonyOS, or Magic UIAffected 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
-
Confirm Wi-Fi functionality is enabledVerify 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
-
Review third-party app permissionsCheck 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] > PermissionsAffected 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply 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.
