CVE-2026-13322

CVE-2026-13322 affects KubeVirt, specifically the virt-handler on RHEL9, where the downward metrics virtio-serial server uses textproto.Reader.ReadLine() to read guest requests. The read is unbounded: there is no maximum length or read deadline, so a user with access to a VM guest can send an ong...

EUVD-2026-39599

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...
