# CVE-2026-62929: CVE-2026-62929

Status: published. Published: 2026-11-10. Updated: 2026-11-13.

Expired pointer dereference in the MigTD's virtio-vsock implementation for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege and information disclosure. System software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
