A flaw was found in DPDK version 19.11 and above that allows a malicious guest to cause a segmentation fault of the vhost-user backend application running on the host, which could result in a loss of connectivity for the other guests running on that host. This is caused by a missing validity check of the descriptor address in the function `virtio_dev_rx_batch_packed()`.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2021:1239 advisory.

    The dpdk packages provide the Data Plane Development Kit, which is a set of libraries and drivers for fast     packet processing in the user space.

    Security Fix(es):

    * dpdk: librte_vhost Malicious guest could cause segfault by sending invalid Virtio descriptor     (CVE-2020-10725)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

The remote NewStart CGSL host, running version MAIN 6.02, has dpdk packages installed that are affected by multiple vulnerabilities:

  - A flaw was found in DPDK version 19.11 and above that allows a malicious guest to cause a segmentation     fault of the vhost-user backend application running on the host, which could result in a loss of     connectivity for the other guests running on that host. This is caused by a missing validity check of the     descriptor address in the function `virtio_dev_rx_batch_packed()`. (CVE-2020-10725)

  - 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. (CVE-2020-10726)

  - A vulnerability was found in DPDK versions 18.05 and above. A missing check for an integer overflow in     vhost_user_set_log_base() could result in a smaller memory map than requested, possibly allowing memory     corruption. (CVE-2020-10722)

  - A memory corruption issue was found in DPDK versions 17.05 and above. This flaw is caused by an integer     truncation on the index of a payload. Under certain circumstances, the index (a UInt) is copied and     truncated into a uint16, which can lead to out of bound indexing and possible memory corruption.
    (CVE-2020-10723)
