CVE-2022-20476

Infinite reboot loop via invalid component settings

Published Dec 13, 2022 · Updated Apr 22, 2025

Resource exhaustion in the Android Framework in Android 10 through 12L allows local users to force a device into an infinite reboot loop. PackageManagerService continues processing nonexistent component names passed to setComponentEnabledSetting and records invalid enabled-state entries, allowing a malicious app to exhaust system_server memory. An installed app needs no additional execution privileges or user interaction, and repeated system-server exhaustion causes persistent local service interruption through reboots.
