CVE-2019-2089

Local privilege escalation via stale shared-ID permissions

Published Mar 15, 2020 · Updated Aug 4, 2024

Elevation of privilege in Google Cloud Android 10 allows local users to gain permissions via incomplete shared-app-ID permission removal during app uninstallation. The uninstall path can leave permissions assigned to a shared application ID instead of removing them, allowing a subsequently installed or remaining app sharing that ID to retain privileges. Exploitation requires user interaction to perform the uninstall workflow; the resulting impact is local privilege escalation affecting confidentiality, integrity, and availability.
