Static analysis and peer reviews catch improper memory handling early, reducing the risk of vulnerabilities reaching production.

Additionally, a defense-in-depth monitoring strategy supports real-time detection of anomalous memory activity, enabling rapid response and limiting potential impact.", "threat_severity": "Moderate"}
