Comment 5 Kiran Darbha 2022-09-23 06:15:07 UTC 
I have this vulnerability shown by Twistlock scans - but its on ubi-minimal 8.6.x. When I check on the Red Hat Advisory here- https://access.redhat.com/security/cve/CVE-2022-23990, it doesn't mention about RHEL v8.x; does that mean, this RHEL v8.x is NOT AFFECTED 
 by this vulnerability(CVE-2022-23990) ??
