CVE-2021-0654

Locked-profile snapshot disclosure via missing permission check

Published Jul 14, 2021 · Updated Aug 3, 2024

Information disclosure in Google Pixel Launcher allows local users to view task snapshots from locked profiles after user interaction. TaskThumbnailView.java's isRealSnapshot method treats a thumbnail as real without enforcing the locked profile's access restriction. Exploitation requires local access and user interaction and exposes snapshot contents across the profile lock boundary without additional execution privileges.
