CVE-2020-10725 is a high-severity vulnerability rated 7.7/10 on the CVSS scale. 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()`.. EPSS estimates a 2.21% chance of exploitation in the next 30 days.
