RHSA-2022:8263: Red Hat Security Advisory: dpdk security and bug fix update

An update for dpdk is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/). If you distribute this content, or a modified version of it, you must provide attribution to Red Hat Inc. and provide a link to the original. 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

CVE-2022-0669: Red Hat Customer Portal - Access to 24x7 support and knowledge

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.

CVE-2021-3839: Invalid Bug ID

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.
