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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","score":3.3},"cwes":["CWE-191"],"references":["http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00004.html","http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00006.html","http://www.openwall.com/lists/oss-security/2021/01/04/1","http://www.openwall.com/lists/oss-security/2021/01/04/2","http://www.openwall.com/lists/oss-security/2021/01/04/5"],"products":["canonical:ubuntu_linux","dpdk:data_plane_development_kit","opensuse:leap"],"source":"nvd","synced_at":"2026-10-19T21:09:53.489947993+00:00"},"epss":{"cve":"CVE-2020-14378","score":0.00397,"percentile":0.33946,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
