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.

The remote MiracleLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2023-5000:03 advisory.

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

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.
