    advisory for the container images for this release:

    https://access.redhat.com/errata/RHBA-2022:0872

    Security Fix(es):

    * CRI-O: Arbitrary code execution in cri-o via abusing
    kernel.core_pattern kernel parameter (CVE-2022-0811)

    For more details about the security issue(s), including the impact, a CVSS
    score, acknowledgments, and other related information, refer to the CVE
    page(s) listed in the References section.

    All OpenShift Container Platform 4.8 users are advised to upgrade to these updated packages and images
    when they are available in the appropriate release channel. To check for available updates, use the
    OpenShift Console or the CLI oc command. Instructions for upgrading a cluster are available at
    https://docs.openshift.com/container-platform/4.8/updating/updating-cluster-cli.html
