CVE-2020-14375: High severity dpdk (data plane development kit) vulnerability
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 vhostcrypto has validated it. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Virtio ring descriptors, and the data they describe are in a region of memory accessible by from both the virtual machine and the host. vhostcrypto.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 vhostcrypto has validated it. vhostcrypto.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.
