CVE-2022-23995

Bedtime mode changes via unprotected alarm receiver

Published Feb 11, 2022 · Updated Aug 3, 2024

Improper access control in Samsung Wearable Devices running Wear OS 3.0 allows attackers to change bedtime mode through an untrusted app. The StBedtimeModeAlarmReceiver component accepts requests from untrusted applications without enforcing the permission needed to protect the receiver. A locally installed application is required, and the bounded consequence is an unauthorized bedtime-mode change rather than data access or code execution.
