Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Red Hat CVSS v3 Score Explanation

There is no impact on integrity as the accuracy of the data is unlikely to be compromised. And while there is a partial loss of confidentiality, the attacker lacks control over the specific information obtained, and the extent and nature of the loss are limited. The disclosed information does not result in a direct, significant harm to the affected component.
