SCA: security update for github.com/kubevirt/kubevirt (GHSA-6f2p-2qg2-qqch)

low Tenable Self-Hosted Container Security Plugin ID 478351

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-13322)

Solution

There is no known solution at this time.
