CVE-2022-20254
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 · uneditedIn Wi-Fi, there is a permissions bypass. This could lead to local escalation of privilege from the guest user with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-223377547
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 confidenceA permissions bypass vulnerability in the Wi-Fi component of Android 13 allows a local guest user to escalate privileges without any additional execution privileges or user interaction. This is a local privilege escalation (LPE) flaw in the Wi-Fi subsystem that enables a guest account to bypass intended permission boundaries.

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.
-
Verify Android versionCheck the device Settings > About Phone > Android version to confirm it is exactly 13.0Affected if The device is running Android 13.0 (not 13.1, 13.2, or later)
-
Check security patch levelNavigate to Settings > About Phone > Security patch level and note the date. Compare against the patch date for A-223377547.Affected if The security patch level is older than the fix date for CVE-2022-20254, meaning the vulnerability has not been addressed
-
Confirm Wi-Fi component is presentVerify the device has Wi-Fi capability enabled by checking Settings > Network & Internet > Wi-Fi is toggled onAffected if Wi-Fi is enabled and the device runs Android 13.0 with an unpatched security level
-
Identify user account type exposureCheck if the device has guest or secondary user accounts configured under Settings > System > Multiple users (or Settings > Accounts > Other users)Affected if A guest or secondary user account exists on an unpatched Android 13.0 device, as the vulnerability enables such accounts to bypass permission boundaries
A user is affected if the device runs Android 13.0 specifically and has not received the security update addressing the Wi-Fi permissions bypass (A-223377547).

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.
dbcve · scopedApply the Android 13 security update that includes the fix for this vulnerability. Organizations should ensure their Android device fleet is receiving and deploying monthly security patches, particularly the patch level that addresses A-223377547.
Android 13 with December 2022 Security Patch Level or later
- 1. Navigate to Settings on the Android device
- 2. Go to System > Software Update (or Security)
- 3. Check for and install any available system updates
- 4. Ensure the device receives the December 2022 Android Security Patch Level or later
- 5. After updating, verify the Wi-Fi permissions behave correctly for guest accounts
