Kerentanan Allocation of Resources Without Limits or Throttling pada redhat openshift virtualization, kubevirt. Skor CVSS 3.1 3.8 (Low) menurut redhat.com.

Deskripsi (NVD)

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.
