CVE-2022-20286
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 Connectivity, there is a possible bypass the restriction of starting activity from background due to a logic error in the code. This could lead to local escalation of privilege with User execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-230866011
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 · high confidenceA logic error in Android's Connectivity component allows bypassing the restriction on starting activities from background, enabling local privilege escalation. The vulnerability requires user execution privileges but does not need user interaction to exploit.

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.
-
Check Android versionGo to Settings > About Phone > Android version, or run `getprop ro.build.version.release` via ADBAffected if The version is exactly 13.0 (the vulnerability affects only this specific version)
-
Verify Android security patch levelGo to Settings > About Phone > Security patch level, or run `getprop ro.build.version.security_patch` via ADBAffected if The security patch level is earlier than the fix release for this CVE (typically December 2022 or earlier) - this helps confirm the system is unpatched
-
Confirm Connectivity service is presentVerify the ConnectivityService is running by checking system logs or using `dumpsys connectivity` via ADBAffected if The Connectivity service is active (this is the component with the logic error, though the vulnerability is inherent to Android 13.0 framework)
A device is affected if it is running Android version 13.0 and has not received the security update that includes the fix for this CVE (typically the December 2022 Android Security Patch Level or later).
Generated from the published advisory. Verify against your own configuration.
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 Android system updates that include the patch for Android-13; this is a framework-level vulnerability that cannot be fixed through application-level remediation.
Android 13 with January 2023 security patch level (2023-01-01) or later
- Open Settings on the Android device
- Navigate to System > Security & privacy > Security update (or Settings > About Phone > Security update on some devices)
- Check the current Android security patch level
- If the security patch level is earlier than January 2023 (2023-01-01), download and install the latest available system update
- After updating, verify the security patch level shows January 2023 or later in Settings > System > Security & privacy > Security update
