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":"2026-06-26T00:16:51.397+00:00","modifiedAt":"2026-10-25T22:10:00.15+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · secalert@redhat.com · Secondary","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:L","score":3.8,"severity":"LOW"}],"references":["https://access.redhat.com/security/cve/CVE-2026-13322","https://bugzilla.redhat.com/show_bug.cgi?id=2492681"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-13322","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-770"],"productCriteria":["cpe:2.3:a:redhat:openshift_virtualization:*:*:*:*:*:*:*:*","cpe:2.3:a:kubevirt:kubevirt:-:*:*:*:*:kubernetes:*:*"],"sourceDates":{"published":"2026-06-26T00:16:51.397","lastModified":"2026-10-25T22:10:00.150"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
