{"id":"AZL-91454","summary":"CVE-2026-13322 affecting package kubevirt 1.8.4-1","details":"A flaw was found in KubeVirt's downward metrics virtio-serial server. 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.","modified":"2026-09-20T05:33:47Z","published":"2026-06-26T00:16:51Z","upstream":["CVE-2026-13322"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-13322"}],"affected":[{"package":{"name":"kubevirt","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kubevirt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.8.4-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-91454.json"}}],"schema_version":"1.9.0"}
