Mitigating Controls (NIST 800-53 r5) AI
Directly mitigates use-after-free exploitation in kernel memory by employing memory protection techniques against unauthorized code execution.
Limits the privileges available to an authorized local attacker, reducing the impact of successful kernel-mode escalation.
Requires timely remediation of the identified use-after-free flaw in the Windows kernel driver before exploitation occurs.
