{"id":"AZL-38821","summary":"CVE-2020-14378 affecting package ceph for versions less than 18.2.2-1","details":"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.","modified":"2026-04-01T05:13:21.169882Z","published":"2020-09-30T19:15:12Z","upstream":["CVE-2020-14378"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-14378"}],"affected":[{"package":{"name":"ceph","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/ceph"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.2.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-38821.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"}]}
