CVE:CVE-2020-24489
CNNVD:CNNVD-202106-630
Intel Virtualization Technology for Direct I/O（Intel VT-d）是美国英特尔（Intel）公司的Intel虚拟化技术的一部分，主要针对的是I/O子系统，它的实现主要是通过在硬件上引入重定向单元，该硬件重定向单元用于对I/O子系统的DMA操作和中断传递进行重定向，从而辅助VMM（Virtual Machine Monitor）实现I/O子系统的虚拟化。
Intel Virtualization Technology for Direct I/O（Intel VT-d）存在授权问题漏洞，该漏洞源于网络系统或产品中缺少身份验证措施或身份验证强度不足。
