Description

A flaw was found in dpdk, which allows a malicious primary vhost-user to attach an unexpected number of fds as ancillary data to VHOST_USER_GET_INFLIGHT_FD / VHOST_USER_SET_INFLIGHT_FD messages that are not closed by the secondary vhost-user. By sending such messages continuously, the primary vhost-user exhausts available fd in the vhost-user standby process, leading to a denial of service.
