While the vulnerability results in a crash of the bgpd daemon, leading to disruption of routing services, it primarily affects the availability aspect of the CIA triad (Confidentiality, Integrity, and Availability). Although the flaw does not directly expose sensitive information or allow unauthorized access to the system, the ability to crash a critical routing component could impact network operations and service availability. However, the exploitation requires a targeted and deliberate action by an attacker, limiting its immediate widespread impact compared to high severity vulnerabilities that could lead to data breaches or complete system compromise.", "threat_severity": "Moderate"}
