02 Description

powerpc/iommu: Fix notifiers being shared by PCI and VIO buses

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: 0.16% probability of exploitation activity in the next 30 days.
EPSS percentile: Ranks above 5.5% of scored records. A rank, not a probability.
NVD base score: 7.0 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
NVD analysis status: Deferred. NVD last modified this record on 2026-08-04.
Red Hat severity: Low. 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.
