Abstract: A method for detecting a memory safety bug and an electronic device supporting the same are provided. The electronic device supporting multiple domains includes memory storing one or more computer programs, and one or more processors communicatively coupled to the memory and operable in a first domain and a second domain, wherein The one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to detect a shared memory use request by the first domain or the second domain, allocate shared memory for communication between multiple domains including the first domain and the second domain based on a memory area designated in the memory, based on the shared memory use request, register a tag for the shared memory in a first memory area of the first domain and a second memory area of the second domain, and detect a memory safety bug for the shared memory shared between the first domain and the second domain, based on the tag.

Abstract: A method and an apparatus for controlling a lock state of an electronic device, and a system therefor are provided. The method includes signing a lock state update request by using a unique key loaded in a confidence region of the electronic device when a lock state change is requested, generating a lock state control request message including the lock state update request, the signed lock state update request, and a certificate of the electronic device, transmitting the generated lock state control request message to a service provider server, and authenticating a lock state update command in a communication processor of the electronic device and updating a state of the communication processor according to the lock state update command when the lock state update command is received from the service provider server.
