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
AC:H - A successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in execution against the vulnerable component before a successful attack can be expected. (Special conditions have to be triggered for the attack vector to exist.) C:L - An attacker does not have control over what information is obtained. I:N - This is a read callback problem, upstream does not document this manipulating data.
