CVE-2026-40693
Quick assessment
Affected
n/a Intel(R) TDX Workload Attestation software
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.
某些英特尔（Intel）TDX（可信执行环境）工作负载证明软件在 Ring 3（用户态）中存在输入验证不当的问题：用户应用程序可能因此导致拒绝服务（DoS）。具备认证用户权限的非特权软件攻击者，若结合高复杂度攻击手段，可能引发拒绝服务。该漏洞在满足攻击条件时，可通过本地访问利用，无需特殊内部知识，且无需用户交互。此潜在漏洞可能影响系统的机密性（无影响）、完整性（无影响）和可用性（高影响），进而导致后续系统机密性（无影响）、完整性（无影响）和可用性（无影响）的进一步影响。

Vulnerability Description
Improper input validation for some Intel(R) TDX Workload Attestation software within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are 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.
