CVE-2023-21175

Guest privilege escalation via mobile-data permission bypass

Published Jun 28, 2023 · Updated Dec 5, 2024

Permissions bypass in Android 13 allows local users with guest access to enable or disable mobile data through system settings. DataUsageSummary.onCreate exposes the mobile-data toggle to a guest profile without enforcing the permission that should block the operation. Guest access alone reaches the control, requires no user interaction, and permits unauthorized changes to cellular connectivity.
