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.","dates":{"published":"2020-09-30T00:00:00.000Z","modified":"2024-08-04T12:46:33.313Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":3.3,"severity":"low","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"OSV
