A vulnerability was found in DPDK versions 19.11 and above. A malicious container that has direct access to the vhost-user socket can keep sending VHOST_USER_GET_INFLIGHT_FD messages, causing a resource leak (file descriptors and virtual memory), which may result in a denial of service.

Acknowledgments: Name: Ferruh Yigit (Reporter) Removed OpenStack 7 affects and added missing affects for OpenStack and Fast Datapath. Only openvswitch2.13+ ships dpdk v19.11+. inflight messages (VHOST_USER_GET_INFLIGHT_FD and VHOST_USER_SET_INFLIGHT_FD) were added in upstream version 19.11 via the following commit: -> https://git.dpdk.org/dpdk/commit/?id=d87f1a1cb7b666550bb53e39c1d85d9f7b861e6f Statement: The versions of DPDK as shipped with Red Hat Enterprise Linux 7 were not affected by this flaw, as they did not include support for the inflight share memory feature, which was introduced in a later version of the package. This issue did not affect the versions of Ceph as shipped with Red Hat Ceph Storage 3 and 4, as they did not include support for DPDK.
