While the vulnerability can lead to service disruption due to daemon crashes, it requires specific conditions to be met for exploitation. An attacker would need to craft OSPF LSA packets with malicious Segment Routing Adjacency SID subTLVs and successfully send them to the vulnerable FRRouting instance. This requires knowledge of the network topology and access to send OSPF packets to the targeted router. Additionally, exploitation may not result in arbitrary code execution, limiting the potential impact.", "threat_severity": "Moderate"}
