CVSS 3.1
3.3 lowCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:LCVE-2020-14378
Low (3.3). EPSS 0.4% chance of exploitation in the next 30 days.
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.
