SSVC decision: Not assessed by CISA
EPSS probability: 7.84% probability of exploitation activity in the next 30 days.
EPSS percentile: Equal to or higher than the score of 94.6% of scored records. A rank, not a probability.
NVD base score: 5.9 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N
NVD analysis status: Modified. NVD last modified this record on 2026-06-17.
Red Hat severity: Moderate. Red Hat's rating for its own products, not a CVSS rating.

Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.
