https://catalog.redhat.com/software/containers/openshift3/jenkins-agent-maven-35-rhel7/5ad9139ebed8bd441305ce98?container-tabs=packages has two xz-libs 5.2.2-1.el7 packages: one for x86_64 and another for i686.

Clair is only finding CVE-2022-1271 for x86_64, but, from what I can tell, the i686 version is also affected.

Either, I'm wrong and it's not affected (very possible) or there is some bug in Claircore.
