Common Vulnerability Scoring System (CVSS) Score Details
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).
The following CVSS metrics and score provided are preliminary and subject to review.
Red Hat | NVD | |
---|---|---|
CVSS v3 Base Score | 5.3 | 7.8 |
Attack Vector | Local | Local |
Attack Complexity | Low | Low |
Privileges Required | None | None |
User Interaction | Required | Required |
Scope | Unchanged | Unchanged |
Confidentiality Impact | Low | High |
Integrity Impact | Low | High |
Availability Impact | Low | High |
