NVD Description

Note: Versions mentioned in the description apply only to the upstream servicemesh-proxy package and not the servicemesh-proxy package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

Envoy is an open source edge and service proxy, designed for cloud-native applications. When a cluster is deleted via Cluster Discovery Service (CDS) all idle connections established to endpoints in that cluster are disconnected. A recursion was introduced in the procedure of disconnecting idle connections that can lead to stack exhaustion and abnormal process termination when a cluster has a large number of idle connections. This infinite recursion causes Envoy to crash. Users are advised to upgrade.
