{"id":"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":"2026-05-18T05:52:20.443323022Z","published":"2020-04-28T20:15:12.717Z","related":["SUSE-SU-2020:1208-1","SUSE-SU-2020:1277-1","openSUSE-SU-2024:14490-1"],"database_specific":{"unresolved_ranges":[{"source":"CPE_FIELD","cpes":["cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:advanced_virtualization:*:*:*"],"extracted_events":[{"last_affected":"8.0"}],"vendor_product":"redhat:enterprise_linux"}]},"references":[{"type":"WEB","url":"https://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=9bf9e0ae6af38c806f4672ca7b12a6b38d5a9581"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/04/msg00000.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/D5GE6ISYUL3CIWO3FQRUGMKTKP2NYED2/"},{"type":"WEB","url":"https://usn.ubuntu.com/4371-1/"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20200518-0003/"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1804548"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1828190"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/libvirt/libvirt","events":[{"introduced":"5e866f7f7ac7aae1dcfc4b74edf24992dd1e85f9"},{"fixed":"df63b6fee9ed7d64349dbd645c993644dda4fde1"}],"database_specific":{"source":"CPE_FIELD","cpe":"cpe:2.3:a:redhat:libvirt:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"4.10.0"},{"fixed":"6.1.0"}]}}],"versions":["v6.1.0-rc2","v6.1.0-rc1","v6.0.0","v6.0.0-rc2","v6.0.0-rc1","v5.10.0","v5.10.0-rc2","v5.10.0-rc1","v5.9.0","v5.9.0-rc1","v5.8.0","v5.8.0-rc2","v5.8.0-rc1","v5.7.0","v5.7.0-rc2","v5.7.0-rc1","v5.6.0","v5.6.0-rc2","v5.6.0-rc1","v5.5.0","v5.5.0-rc2","v5.5.0-rc1","CVE-2019-10168","CVE-2019-10161","CVE-2019-10166","CVE-2019-10167","v5.4.0","v5.4.0-rc2","v5.4.0-rc1","v4.10.0","v5.0.0","v5.2.0","CVE-2019-10132","v5.3.0","v5.3.0-rc2","v5.3.0-rc1","CVE-2019-3886","v5.2.0-rc2","v5.2.0-rc1","v5.1.0","v5.1.0-rc2","v5.1.0-rc1","v5.0.0-rc2","v5.0.0-rc1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2020-12430.json"}},{"ranges":[{"type":"GIT","repo":"https://gitlab.com/libvirt/libvirt","events":[{"introduced":"5e866f7f7ac7aae1dcfc4b74edf24992dd1e85f9"},{"fixed":"df63b6fee9ed7d64349dbd645c993644dda4fde1"}],"database_specific":{"source":"CPE_FIELD","cpe":"cpe:2.3:a:redhat:libvirt:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"4.10.0"},{"fixed":"6.1.0"}]}}],"versions":["v6.1.0-rc2","v6.1.0-rc1","v6.0.0","v6.0.0-rc2","v6.0.0-rc1","v5.10.0","v5.10.0-rc2","v5.10.0-rc1","v5.9.0","v5.9.0-rc1","v5.8.0","v5.8.0-rc2","v5.8.0-rc1","v5.7.0","v5.7.0-rc2","v5.7.0-rc1","v5.6.0","v5.6.0-rc2","v5.6.0-rc1","v5.5.0","v5.5.0-rc2","v5.5.0-rc1","CVE-2019-10168","CVE-2019-10161","CVE-2019-10166","CVE-2019-10167","v5.4.0","v5.4.0-rc2","v5.4.0-rc1","v4.10.0","v5.0.0","v5.2.0","CVE-2019-10132","v5.3.0","v5.3.0-rc2","v5.3.0-rc1","CVE-2019-3886","v5.2.0-rc2","v5.2.0-rc1","v5.1.0","v5.1.0-rc2","v5.1.0-rc1","v5.0.0-rc2","v5.0.0-rc1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2020-12430.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
