CVE-2024-4437: Red Hat Openstack Platform 16.1

High severity, CVSS 7.5. EPSS: 0.8% chance of exploitation in the next 30 days.

The etcd package distributed with the Red Hat OpenStack platform has an incomplete fix for CVE-2021-44716. This issue occurs because the etcd package in the Red Hat OpenStack platform is using http://golang.org/x/net/http2 instead of the one provided by Red Hat Enterprise Linux versions, meaning it should be updated at compile time instead.
