cos is failing because of the on-going kernel-packer problems. It should pass, like all the other platforms, once we have kernel sources.

Not sure about the arm failures:

Collector Version: 3.18.x-143-gd8d9f8ceaf
OS: Red Hat Enterprise Linux 9.3 (Plow)
Kernel Version: 5.14.0-362.18.1.el9_3.aarch64
Starting StackRox Collector...
/usr/local/bin/collector-wrapper.sh: line 5: /usr/local/bin/collector: cannot execute binary file: Exec format error
/usr/local/bin/collector-wrapper.sh: line 5: /usr/local/bin/collector: Success

Implies that we're trying to run non-arm64 images
