Denial of Service Vulnerability in Intel TDX Migration Trust Domain

CVE-2026-62930

What is CVE-2026-62930?

The vulnerability arises from an unchecked return value in the TLS implementation of the Intel TDX Migration Trust Domain (MigTD) which operates within Ring 0. This flaw may lead to a denial of service when exploited by a network adversary with unauthenticated access. An attacker can initiate a low complexity attack that may potentially disrupt the availability of the system. Exploitation of this vulnerability does not require special internal knowledge or user interaction, making it feasible under certain conditions. While the confidentiality and integrity impacts are minimal, the disruption to system availability can result in significant operational challenges.
