CVE-2022-20263
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 ActivityManager, there is a way to read process state for other users due to a missing permission check. This could lead to local information disclosure of app usage with User execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-217935264
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 confidenceIn Android's ActivityManager, a missing permission check allows reading process state information for other users on the device. This enables local information disclosure of app usage data belonging to other users without requiring user interaction.

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.
-
Confirm Android version is 13.0Run 'adb shell getprop ro.build.version.release' or check Settings > About Phone > Android versionAffected if Version displays as exactly 13.0 (the only affected version listed)
-
Verify multi-user functionality is enabledRun 'adb shell pm list users' to list user accounts on the deviceAffected if Multiple user accounts exist on the device (the vulnerability enables reading process state for other users)
-
Inspect ActivityManager process information exposureRun 'adb shell dumpsys activity processes' and check if process details for user accounts other than the current user are visible without elevated permissionsAffected if Process state information for other user accounts is accessible without proper authorization checks
Device is affected if running Android 13.0 with multi-user accounts enabled, allowing unauthorized access to other users' app process information through the unprotected ActivityManager component

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 security patch for Android-13 that addresses this vulnerability. Organizations should verify their devices have received the relevant vendor security update.
Android 14 or Android 13 with October 2022+ security patch level
- Go to Settings > System > Software Update on the device
- Check for and install any available system updates
- Ensure the security patch level is October 2022 or later (check in Settings > About Phone > Security Patch Level)
- If no update available, consider upgrading to Android 14 which includes all recent security fixes
