What is CVE-2026-62920?

The TDX Migration Trust Domain (MigTD) in Intel's hypervisor is vulnerable due to unchecked return values in error handling routines. This oversight could allow an attacker with privileged access to execute a low-complexity local attack, leading to a potential denial of service. The nature of the vulnerability requires no special internal knowledge and no user interaction, which makes it particularly concerning for system availability. If exploited, this vulnerability could disrupt services and significantly impact the operational capacity of affected systems.
