CVE:CVE-2013-5740
CNNVD:CNNVD-201309-182
Intel Trusted Execution Technology（TXT，英特尔可信任执行技术）是美国英特尔（Intel）公司酷睿2双核处理器中的一项硬件延伸技术，主要用于保护虚拟化计算环境中的数据，可避免受到间谍软件攻击、病毒入侵等威胁。
Intel和Mobile Intel芯片中使用的Intel TXT中的SINIT Authenticated Code Modules (ACM)组件1.2之前的版本中存在提权漏洞。当已度量加载环境(measured launch environment,简称MLE)被调用，本地攻击者可利用该漏洞绕过TXT保护机制，执行SINIT ACM功能。
