MEDIUM

Red Hat OpenShift - ResourceQuota Bypass Event Flood Denial of Service

Title source: manual
STIX 2.1

Description

A flaw was found in OpenShift Container Platform. Completed pods with restartPolicy: Never do not count toward ResourceQuota pod limits, and Kubernetes events are not quota-scoped. A non-privileged user who can create pods in a namespace can exploit this to generate a large volume of events that accumulate in etcd, causing API server performance degradation across the cluster.
