CVE-2026-63027
Quick assessment
Affected
n/a Intel(R) TDX Migration Trust Domain (MigTD)
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Ring 0（内核态）环境中，Intel(R) TDX 迁移信任域（MigTD）的 函数存在执行顺序错误：Hypervisor（虚拟机监控器）可能因此导致拒绝服务（DoS）。网络攻击者若以未认证用户身份发起低复杂度攻击，即可触发该拒绝服务漏洞。该漏洞可能在相邻访问场景下被利用，且无需特殊内部知识或用户交互。此潜在漏洞对受影响系统的机密性（无影响）、完整性（无影响）和可用性（低影响）构成威胁，但不会引发后续的系统机密性、完整性或可用性方面的连锁影响。

Vulnerability Description
Incorrect behavior order in the get_tcb_level_by_svn 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 (none) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
