{"id":"AZL-70187","summary":"CVE-2025-12748 affecting package libvirt for versions less than 10.0.0-7","details":"A flaw was discovered in libvirt in the XML file processing. More specifically, the parsing of user provided XML files was performed before the ACL checks. A malicious user with limited permissions could exploit this flaw by submitting a specially crafted XML file, causing libvirt to allocate too much memory on the host. The excessive memory consumption could lead to a libvirt process crash on the host, resulting in a denial-of-service condition.","modified":"2026-04-21T04:36:20.753747Z","published":"2025-11-11T20:15:34Z","upstream":["CVE-2025-12748"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-12748"}],"affected":[{"package":{"name":"libvirt","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libvirt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.0.0-7"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-70187.json"}}],"schema_version":"1.7.5"}
