Randomize the kernel memory sections
Medium Severity
Randomizes the base virtual address of kernel memory sections (physical memory mapping, vmalloc & vmemmap). This configuration is available from kernel 4.8, but may be available if backported by distros. The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_RANDOMIZE_MEMORY
, run the following command:
grep CONFIG_RANDOMIZE_MEMORY /boot/config-*
For each kernel installed, a line with value "y" should be returned.
