Title:
ELECTRONIC DEVICE AND METHOD FOR CONTROLLING OPERATION OF KERNEL CODE AREA
Document Type and Number:
WIPO Patent Application WO/2024/048922
Kind Code:
A1
Abstract:
An electronic device for controlling the operation of a kernel code area according to an embodiment may include a processor which: in machine mode, configures a range register on the basis of the physical address of the kernel code area in which a kernel code is stored; in kernel mode, uses a page table entry for a virtual address of a page to acquire the physical address of the page in response to a case in which the processor receives an access request based on the virtual address of the page; determines whether an area corresponding to the acquired physical address is included in the kernel code area by comparing the configured range register with the acquired physical address; and determines whether to enable or disable at least one of a write operation or an execution operation for the area corresponding to the physical address on the basis of whether the area corresponding to the acquired physical address is included in the kernel code area.
