Service interruption via malicious content provider
Published Nov 5, 2021 · Updated Aug 3, 2024
Improper authentication in Samsung Health before 6.19.1.0001 allows local users to interrupt the app via a malicious content provider. The published record says only that Samsung Health accesses a non-existent provider through a malicious content provider; it names no code-level locus or failing operation. A malicious content provider on the same Android device is required, and the documented consequence is a service interruption without data disclosure or modification.
