CVE-2026-61467 · Severity: info · Published 2026-11-10

Intel's TDX Migration Trust Domain (MigTD) is a hypervisor component that enables secure virtual machine migration with confidential computing. A use-after-free vulnerability in the virtio driver could allow a privileged attacker to corrupt data and escalate their privileges within the hypervisor. An exploit requires system-level access and would compromise the integrity of the virtualized environment.
