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.

CVE-2020-14374 DPDK vulnerabilities
Title: DPDK vulnerabilities
Summary: Several security issues were fixed in DPDK.
Ryan Hall discovered that DPDK incorrectly handled vhost crypto. An
attacker inside a guest could use these issues to perform multiple attacks,
including denial of service attacks, obtaining sensitive information from
the host, and possibly executing arbitrary code on the host.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2020-14375 dpdk: time-of-check time-of-use vulnerabilities throughout vhost_crypto.c
Virtio ring descriptors, and the data they describe are in a region of memory accessible by from both the virtual machine and the host. vhost_crypto.c frequently accesses the descriptors directly in the shared memory region. This is not safe. An attacker in the VM can change the contents of the memory after vhost_crypto has validated it. vhost_crypto.c needs to avoid processing data directly in the shared memory region. This can be exploited in the same way as finding number 1 to gain remote code execution and virtual machine escape.
