CVE-2025-48534

Local service interruption via unrestricted receiver query

Published Sep 4, 2025 · Updated Sep 5, 2025

Denial of service in Android 13 through 15 allows local users with System execution privileges to interrupt Cell Broadcast delivery. The getDefaultCBRPackageName method queries broadcast receivers without MATCH_SYSTEM_ONLY, allowing a fake receiver to enter default-package selection. Exploitation requires System execution privileges and no user interaction, and the reported consequence is local service interruption.
