The server reads guest requests using textproto.Reader.ReadLine(), which buffers input indefinitely until a newline character is received, with no length limit or read deadline. A user with access to a VM guest that has the downward metrics virtio-serial device configured can write a continuous byte stream to the device, causing unbounded memory allocation in the virt-handler process until it is OOM-killed.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:L","score":3.8,"severity":null}],"references":["https://access.redhat.com/security/cve/CVE-2026-13322","https://bugzilla.redhat.com/show_bug.cgi?id=2492681"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-39599","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Jun 26, 2026, 12:04:07 AM","dateUpdated":"Jun 26, 2026, 1:39:15 PM"},"relatedAdvisories":[{"id":"msrc_CVE-2026-13322","title":"Kubevirt: virt-handler-rhel9: kubevirt: unbounded virtio-serial readline in virt-handler causes oom denial of service","vulnerabilityIds":["CVE-2026-13322"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
