    Runc: volume mount race condition (regression of cve-2019-19921) (cve-2023-27561).
    Runc: apparmor can be bypassed when `/proc` inside the container is symlinked with a specific mount configuration (cve-2023-28642).
    Runc: integer overflow in netlink bytemsg length field allows attacker to override netlink-based container configuration (cve-2021-43784).
