Severity scores defined by OISF and CVSS may vary due to how assess and evaluate impact. While CVSS has a more generic view on vulnerabilities and will penalize any network-related issues, for instance, OISF considers Suricata context as the baseline (thus, as example, affecting the network isn’t taken into account).
