CONFIG_RANDOMIZE_MEMORY: Randomize the kernel memory sections

General informations

The Linux kernel configuration item CONFIG_RANDOMIZE_MEMORY:

Help text

Randomizes the base virtual address of kernel memory sections (physical memory mapping, vmalloc & vmemmap). This security feature makes exploits relying on predictable memory locations less reliable.

The order of allocations remains unchanged. Entropy is generated in the same way as RANDOMIZE_BASE. Current implementation in the optimal configuration have in average 30,000 different possible virtual addresses for each memory section.

If unsure, say N.
