{"id":"CVE-2026-62930","kind":"vulnerability","aliases":["CVE-2026-62930"],"related":[],"title":"Intel TDX MigTD TLS: unchecked return value allows denial of service","description":"Unchecked return value in the MigTD's TLS implementation for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent 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 (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.","summary":"The TLS code in Intel's MigTD migration component for TDX confidential VMs does not check a return value.
