Linux Kernel \'EFER_LME\'本地拒绝服务漏洞

BUGTRAQ ID: 34331 CNCAN ID：CNCAN-2009040206 Linux是一款开放源代码的操作系统。 I386的Linux上限制EFER访问存在问题，本地攻击者可以利用漏洞对系统进行拒绝服务攻击。 vmxsetmsr不允许i386客户访问EFER，但是仍旧可以通过switch中的default:标签来访问，如果它们设置了EFERLME，可导致触发内核oops，产生拒绝服务攻击。 Linux kernel 2.6.28 9 Linux kernel 2.6.28 8 Linux kernel 2.6.28 6 Linux kernel 2.6.28 5 Linux...
