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
AV:N because libexif can be used to parse EXIF data on a server or machine accepting input from network. PR:N because in such a scenario, there would likely be no privileges required. C:L because the out-of-bounds read is limited to only a few bytes per entry. A:L because out-of-bounds reads are undefined behavior which could potentially cause a crash.
