AI analysisSummaries by Vani AI
A missing critical authentication step in the MigTD SPDM rebind path of Intel TDX Migration Trust Domain (Ring 0 hypervisor) can allow privilege escalation, information disclosure, and remote code execution. An unauthenticated attacker on an adjacent network can trigger it with low complexity and no user interaction. Confidentiality, integrity, and availability of the vulnerable system and subsequent systems may be fully compromised. Intel has not listed affected builds.
What to do: Apply Intel's update for CVE-2026-61887. No workaround is stated.

Description · NVD
Missing critical step in authentication in the MigTD SPDM rebind implementation for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege and information disclosure. Network adversary with an unauthenticated user combined with a low complexity attack may enable remote code execution. 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 (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (high) impacts.
