Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GHSA-9m94-w2vq-hcf9 affects kubevirt.io/kubevirt versions before 1.7.0-beta.0. An attacker who can obtain the UID of a running VMI and create a pod in the same namespace can give it labels that make virt-controller associate the pod with that VMI, which can lead to incorrect status updates and a denial of service for the VMI. Upgrade to kubevirt.io/kubevirt 1.7.0-beta.0 or later. The source gives few details on workarounds.
