1.7 UBTU-22-213025

Information

The operating system must implement nonexecutable data to protect its memory from unauthorized code execution.

GROUP ID: V-260475
RULE ID: SV-260475r958928

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.

Solution

Configure the operating system to enable NX.

If the installed CPU is hardware capable of NX protection, check if the system's BIOS/UEFI setup configuration permits toggling the "NX bit" or "no execution bit", and set it to "enabled".
