Comment 12 Christopher Lusk 2026-08-03 14:31:45 UTC 
PSIRTSUPT-20948: TAM flagged that OCP 4.20 was missing from the CVE page. Investigation confirmed that active streams openshift-4.20, openshift-4.21, and openshift-4.22 had no affects filed, despite shipping the same vulnerable samba RPMs via RHCOS (RHEL 9.6 base). Added AFFECTED/DELEGATED affects for all three streams to match the existing pattern (openshift-4.12.z through openshift-4.19).
