Synopsis

The remote Red Hat CoreOS host is missing a security update for OpenShift Container Platform 4.13.29.

Description

The remote Red Hat Enterprise Linux CoreOS 4 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2024:0195 advisory.

 - A flaw was found in CRI-O that involves an experimental annotation leading to a container being unconfined. This may allow a pod to specify and get any amount of memory/cpu, circumventing the kubernetes scheduler and potentially resulting in a denial of service in the node. (CVE-2023-6476)
