11. A memory management method for security in an electronic device, comprising:
obtaining, from a kernel, at least one address for a first memory area accessible through the kernel;
storing the at least one address in a second memory area accessible through a hypervisor;
based on obtaining an address stored in a kernel stack from the kernel, identifying whether the obtained address is defective based on the stored at least one address; and
recovering the defective address using at least one address stored in the second memory area in response to identifying the defect in the obtained address.
