Weight

Fix Recommendation

Remove the "kernel.randomize_va_space" entry found in the "/etc/sysctl.conf" file or any file located in the "/etc/sysctl.d/" directory.

After the line has been removed, the kernel settings from all system configuration files must be reloaded before any of the changes will take effect. Run the following command to reload all of the kernel system configuration files:

$ sudo sysctl --system

Check Contents

Verify Ubuntu 24.04 LTS implements address space layout randomization (ASLR) with the following command:

$ sysctl kernel.randomize_va_space
kernel.randomize_va_space = 2

If nothing is returned, verify the kernel parameter "randomize_va_space" is set to "2" with the following command:

$ cat /proc/sys/kernel/randomize_va_space
2

If "kernel.randomize_va_space" is not set to "2", this is a finding.

Verify that a saved value of the "kernel.randomize_va_space" variable is not defined.

$ sudo egrep -R "^kernel.randomize_va_space=[^2]" /etc/sysctl.conf /etc/sysctl.d

If this returns a result, this is a finding.
