Related CVEs: * CVE-2021-3839: DPDK: out-of-bounds read/write in vhost_user_set_inflight_fd() may lead to crash * CVE-2022-2132: dpdk: DoS when a Vhost header crosses more than two descriptors and exhausts all mbufs * CVE-2022-28199: dpdk: error recovery in mlx5 driver not handled properly, allowing for denial of service

A flaw was found in dpdk. This flaw allows a malicious vhost-user master 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 vhost-user slave. By sending such messages continuously, the vhost-user master exhausts available fd in the vhost-user slave process, leading to a denial of service.

A flaw was found in the vhost library in DPDK. Function vhost_user_set_inflight_fd() does not validate `msg->payload.inflight.num_queues`, possibly causing out-of-bounds memory read/write. Any software using DPDK vhost library may crash as a result of this vulnerability.

Red Hat Security Advisory 2022-4788-01 - Open vSwitch provides standard network bridging functions and support for the OpenFlow protocol for remote per-flow control of traffic. Issues addressed include denial of service and out of bounds read vulnerabilities.
