All IBM WMLCE distribution channels have been updated. For those using containers, pulling the image again from its upstream container registry (<https://hub.docker.com/r/ibmcom/powerai&gt;, <https://catalog.redhat.com>, etc) will download an updated image with CVEs resolved. All others should update directly from our conda channel via conda update.
