The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the dpdk-21.11.1-1.el9 build changelog.

  - 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. (CVE-2021-3839)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to the versions of the dpdk packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - DPDK: out-of-bounds read/write in vhost_user_set_inflight_fd() may lead to crash (CVE-2021-3839)

  - dpdk: sending vhost-user-inflight type messages could lead to DoS (CVE-2022-0669)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2022:4787 advisory.

    Open vSwitch provides standard network bridging functions and support for the OpenFlow protocol for remote     per-flow control of traffic.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0071 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2022-0669:
    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:
    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.
