Given that Ollama is often used in production environments for AI model serving, an attacker can repeatedly exploit this flaw to persistently crash the server, leading to significant downtime, operational disruptions, and potential financial loss. Furthermore, if the crash occurs in a shared or cloud-hosted environment, it could impact multiple users, escalating the overall risk.", "threat_severity": "Important"}
