CVE-2022-20309

Installed-app disclosure via PackageInstaller side channel

Published Aug 11, 2022 · Updated Aug 3, 2024

Information disclosure in Android 13 PackageInstaller allows local users to determine whether another app is installed without query permission. Google identifies a side channel in PackageInstaller but has not published the underlying operation or signal that reveals package presence. A local app needs no additional execution privileges or user interaction; the disclosed result is limited to whether a targeted app is installed.
