CVE-2022-2132

dpdk: DoS when a Vhost header crosses more than two descriptors and exhausts all mbufs

A permissive list of allowed inputs flaw was found in DPDK. This issue allows a remote attacker to cause a denial of service triggered by sending a crafted Vhost header to DPDK.

CVE-2022-0669

dpdk: sending vhost-user-inflight type messages could lead to DoS

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

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

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-2020-14378

dpdk: partial Denial of Service due to Integer Underflow

An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the `move_desc` function can lead to large amounts of CPU cycles being eaten up in a long running loop. An attacker could cause `move_desc` to get stuck in a 4,294,967,295-count iteration loop. Depending on how `vhost_crypto` is being used this could prevent other VMs or network tasks from being serviced by the busy DPDK lcore for an extended period.

CVE-2020-14377

dpdk: write_back_data buffer over read (cipher->para.dst_data_len & desc->len)

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A complete lack of validation of attacker-controlled parameters can lead to a buffer over read. The results of the over read are then written back to the guest virtual machine memory. This vulnerability can be used by an attacker in a virtual machine to read significant amounts of host memory. The highest threat from this vulnerability is to data confidentiality and system availability.

CVE-2020-14376

dpdk: buffer overflow copying iv_data from guest to host (prepare_sym_cipher_op & prepare_sym_chain_op)

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A lack of bounds checking when copying iv_data from the VM guest memory into host memory can lead to a large buffer overflow. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CVE-2020-14375

dpdk: time-of-check time-of-use vulnerabilities throughout vhost_crypto.c

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. Virtio ring descriptors, and the data they describe are in a region of memory accessible by from both the virtual machine and the host. An attacker in a VM can change the contents of the memory after vhost_crypto has validated it. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

dpdk: remote Code Execution in vhost_crypto (VM Escape)

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A flawed bounds checking in the copy_data function leads to a buffer overflow allowing an attacker in a virtual machine to write arbitrary data to any address in the vhost_crypto application. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CVE-2020-10726

dpdk: librte_vhost VHOST_USER_GET_INFLIGHT_FD message flooding to result in a DoS

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-2020-10725

dpdk: librte_vhost Malicious guest could cause segfault by sending invalid Virtio descriptor

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()`.

dpdk: librte_vhost Missing inputs validation in Vhost-crypto

A vulnerability was found in DPDK versions 18.11 and above. The vhost-crypto library code is missing validations for user-supplied values, potentially allowing an information leak through an out-of-bounds memory read.

CVE-2020-10723

dpdk: librte_vhost Integer truncation in vhost_user_check_and_alloc_queue_pair()

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.

dpdk: possible memory leak leads to denial of service

A flaw was found in all dpdk version 17.x.x before 17.11.8, 16.x.x before 16.11.10, 18.x.x before 18.11.4 and 19.x.x before 19.08.1 where a malicious master, or a container with access to vhost_user socket, can send specially crafted VRING_SET_NUM messages, resulting in a memory leak including file descriptors. This flaw could lead to a denial of service condition.

CVE-2018-1059

dpdk: Information exposure in unchecked guest physical to host virtual address translations

The DPDK vhost-user interface does not check to verify that all the requested guest physical range is mapped and contiguous when performing Guest Physical Addresses to Host Virtual Addresses translations. This may lead to a malicious guest exposing vhost-user backend process memory. All versions before 18.02.1 are vulnerable.
