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
In wlan driver, there is a possible missing bounds check. This could lead to local denial of service in wlan services.

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 · low confidence

A missing bounds check in the WLAN driver allows a local attacker to trigger a denial of service through memory corruption. The vulnerability stems from insufficient validation of input data sizes before memory operations, potentially allowing out-of-bounds access.

MitigationApply vendor-supplied patches for the WLAN driver. Until patch availability, monitor for unusual WLAN service disruptions and restrict local untrusted code execution.

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. Check Android OS version
    Go to Settings > About Phone > Android version or run 'getprop ro.build.version.release' via ADB
    Affected if The version is 10.0, 11.0, or 12.0
  2. Verify WLAN is enabled
    Check Settings > Network & Internet > Wi-Fi is turned on, or run 'settings get global wifi_on' via ADB
    Affected if WLAN is enabled and the device is on an affected Android version
  3. Check WLAN driver version
    Run 'wpa_cli status' or check '/proc/net/wireless' via ADB to inspect driver information
    Affected if The WLAN driver is present and the device runs an affected Android version
  4. Review WLAN service logs for crashes
    Run 'logcat -d | grep -i wlan' or check 'dmesg' via ADB for memory corruption or bounds check error messages
    Affected if Repeated WLAN service crashes or memory corruption errors appear in logs

If the device runs Android 10.0, 11.0, or 12.0 with WLAN enabled and exhibits unexplained WLAN driver crashes or memory errors, the environment is likely affected by CVE-2022-44444.
