{"id":"ALPINE-CVE-2020-12430","details":"An issue was discovered in qemuDomainGetStatsIOThread in qemu/qemu_driver.c in libvirt 4.10.0 though 6.x before 6.1.0. A memory leak was found in the virDomainListGetStats libvirt API that is responsible for retrieving domain statistics when managing QEMU guests. This flaw allows unprivileged users with a read-only connection to cause a memory leak in the domstats command, resulting in a potential denial of service.","modified":"2026-09-11T10:17:51.369158334Z","published":"2020-04-28T20:15:12.717Z","upstream":["CVE-2020-12430"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-12430"}],"affected":[{"package":{"name":"libvirt","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/libvirt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.10.0"},{"fixed":"5.5.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12430.json"}},{"package":{"name":"libvirt","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/libvirt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.10.0"},{"fixed":"5.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12430.json"}},{"package":{"name":"libvirt","ecosystem":"Alpine:v3.8","purl":"pkg:apk/alpine/libvirt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.10.0"},{"fixed":"5.5.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12430.json"}},{"package":{"name":"libvirt","ecosystem":"Alpine:v3.9","purl":"pkg:apk/alpine/libvirt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.10.0"},{"fixed":"5.5.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12430.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
