Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy&#8217;s ProdClusterManagerFactory::allocateConnPool dereferences transport_socket_options while selecting an HTTP\/3 connection pool without first checking whether the pointer is null. LoadBalancerContext implementations used by synthetic, mirror, health-check, and async-client calls can return no transport-socket options. With auto_config and HTTP\/3 enabled, routine traffic reaching one of those contexts can crash an Envoy worker. The relevant scope boundary is that the affected branch requires HTTP\/3 in the protocol set and a context that supplies no transport-socket options. This issue is fixed in versions 1.36.10, 1.37.6, 1.38.4, and 1.39.1.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Envoy is an open source edge and service proxy designed for cloud-native applications.
