CVE-2020-10726

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.

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.
