Mitigating Controls (NIST 800-53 r5) AI
Directly enforces validation of untrusted file inputs (e.g., images/fonts processed by Skia) to reject malformed data that triggers out-of-bounds reads.
Applies memory-protection mechanisms that block unauthorized reads beyond allocated buffers, mitigating the exact CWE-125 flaw in Chrome's renderer.
Process isolation (as used by Chrome sandboxing) confines any successful memory disclosure to the compromised renderer process, limiting exfiltration of sensitive data.

Secure-development practices such as bounds checking and memory-safe languages directly prevent out-of-bounds reads.
Vulnerability scanning and recording can discover instances of out-of-bounds reads after code is deployed.
Routine patching replaces vulnerable code containing out-of-bounds read flaws.

Security testing in development and acceptance includes fuzzing and static analysis that detect out-of-bounds read defects before release.
Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.
Secure development life cycle mandates input validation and bounds checking that directly prevent out-of-bounds reads.
Application security requirements include explicit bounds and memory-safety specifications that mitigate buffer over-reads.
Secure system architecture and engineering principles require memory-safe design patterns and runtime protections against out-of-bounds access.
Secure coding standards explicitly forbid unsafe pointer arithmetic and mandate bounds-checked reads, eliminating CWE-125.
