The Verge报道，英特尔处理器再曝新的名为ZombieLoad安全漏洞。该漏洞由格拉茨理工大学的研究人员发现，并向英特尔公司披露。英特尔已经发布了修复这一漏洞的代码，不过它必须通过制造商执行，然后由用户安装补丁。
ZombieLoad允许黑客窃取处理器最近访问过的任何数据。即使在云计算服务器上也是如此。该漏洞影响到2011年以来的所有英特尔芯片，微软、苹果和谷歌目前都已经发布更新。由于黑客必须在机器上运行代码才能利用ZombieLoad，所以该漏洞并不是每个人都面临的迫在眉睫的风险。
在此前的Spectre和Meltdown两大安全漏洞中，研究人员便表示预测执行进程留下了许多漏洞，黑客可以利用它们发动攻击。而如今的ZombieLoad同样利用了大多数现代处理器的内置进程——预测执行（speculative execution）。该特性允许处理器以“先发制人”的方式执行未来的命令，从而提高了速度。
修复这些漏洞，需要对处理器进行补丁更新，这会使它们的速度稍微减慢。但是修复并不能完全切断遭受攻击的可能性，预测执行是研究人员认为会不断发现漏洞的领域。也就是说，在不改变机制的情形下，后续还可能曝出一系列可能存在的安全漏洞。
此前英特尔由于处理器性能提升的缓慢一直被视为挤牙膏。而本来因为此前漏洞而使得性能有所下降的英特尔，这次再次遭遇新的漏洞，也难怪网友直言：牙膏又被吸了回去。
