CVE-2022-20285

Installed-app disclosure via PackageManager side channel

Published Aug 11, 2022 · Updated Aug 3, 2024

Information disclosure in Android 13 PackageManager allows local users to determine whether another app is installed without query permission. PackageManager exposes a side channel that answers an installed-app query even when the caller lacks package-visibility permission. A low-privileged locally running app can perform the check without user interaction, exposing installed-application inventory but not app data.
