The problem is openscanhub appears to run on a RHEL-9 host and the
RHEL-9 kernel doesn't support the sandboxing that xz just enabled:

  https://bugzilla.redhat.com/show_bug.cgi?id=2407105

IMHO that isn't a bug that openscanhub must solve. This needs to be
addressed in xz. The widespread use of containers means code must
not assume kernel features detected at build time are still valid at
runtime.

With regards,
Daniel
