RedHat: RHSA-2022-0996:01 Moderate: Red Hat OpenStack Platform 16.2
Summary
OpenStack Networking (neutron) is a virtual network service for OpenStack.
Just as OpenStack Compute (nova) provides an API to dynamically request and
configure virtual servers, OpenStack Networking provides an API to
dynamically request and configure virtual networks. These networks connect
'interfaces' from other OpenStack services (e.g. virtual NICs from Compute
VMs). The OpenStack Networking API supports extensions to provide advanced
network capabilities (e.g. QoS, ACLs, network monitoring, etc.)
Security Fix(es):
* Routes middleware memory leak for nonexistent controllers(CVE-2021-40797)
