CVE-2026-61383
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 Intel(R) TDX 迁移信任域（MigTD）的 Ring 0 环境中，MigTD 的 函数存在缓冲区大小计算错误。该漏洞可能导致超visor 允许发生拒绝服务（DoS）攻击。具备未认证用户权限且能实施高复杂度攻击的系统软件攻击者，可在无需特殊内部知识、无需用户交互的情况下，通过本地访问触发此拒绝服务。该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（影响程度：低）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 Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
Incorrect calculation of buffer size in the MigTD's servtd_get_quote 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 high 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 (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
