for the Open Container Project, often used with Docker. The Netlink

Netlink-based container configurations. This vulnerability required the
attacker to have some control over the configuration of the container, but
would have allowed the attacker to bypass the namespace restrictions of
the container by simply adding their own Netlink payload which disables
all namespaces. (CVE-2021-43784)");
