CVE-2025-21058 is an improper access control vulnerability in Samsung's Routines automation component on Galaxy devices. It affects Routines versions prior to 4.8.7.1 on Android 15 and prior to 4.9.6.0 on Android 16. According to the provided content, the flaw is caused by insufficient authorization checks in Routines, which exposed privileged operations to local processes without properly validating caller identity or permissions. A local attacker on the device could abuse this weakness to execute arbitrary code in a SystemUI-privileged context, crossing the intended boundary between ordinary applications and system-level components.
