CONFIG_MEM_SAFE_NUM_EXTRA_REGIONS:

The functions available in mem_safe.h check if memory is within read-only or read-write regions before accessing it instead of crashing. The kernel image is added as a valid region automatically, but other regions can be added if the application makes access to additional memory outside of the image’s boundaries.
