03 Exploitation and scoring

Exploitation: Not assessed. CISA has not published an exploitation assessment for this record, and it is not in the KEV catalog. That is an absence of assessment, not a finding of no risk.
SSVC decision: Not assessed by CISA
EPSS probability: 82.19% probability of exploitation activity in the next 30 days.
EPSS percentile: Equal to or higher than the score of 99.6% of scored records. A rank, not a probability.
NVD base score: The NVD has published no score for this record
NVD CVSS vector: No NVD score to derive
NVD analysis status: Modified. NVD last modified this record on 2026-06-16.
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.
