Some adversaries launch attacks with the intent of executing code in nonexecutable regions of memory or in memory locations that are prohibited. Security safeguards employed to protect memory include, for example, data execution prevention and address space layout randomization. Data execution prevention safeguards can either be hardware-enforced or software-enforced, with hardware providing the greater strength of mechanism. Examples of attacks are buffer overflow attacks.

Fix:Configure the SUSE operating system to prevent leaking of internal kernel addresses by running the following command: > sudo sysctl -w kernel.kptr_restrict=1 If "1" is not the system's default value, add or update the following line in "/etc/sysctl.d/99-stig.conf": > sudo sh -c 'echo "kernel.kptr_restrict=1" >> /etc/sysctl.d/99-stig.conf' > sudo sysctl --system
