Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly addresses the CVE by requiring timely patching of the specific use-after-free vulnerability in Chrome's GPU component.

SC-39 Process Isolation partial match
prevent

Strengthens browser sandboxing through process isolation, limiting the scope and impact of potential sandbox escapes triggered by the GPU use-after-free.

SI-16 Memory Protection partial match
prevent

Implements memory safeguards like non-executable memory and ASLR that hinder reliable exploitation of the use-after-free vulnerability in the GPU.
