CVE-2026-55709

Description

Loop with unreachable exit condition ('infinite loop') in the MigTD's GetQuote for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow a denial of service. System software adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. 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 (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
