Linux kernel built with the KVM visualization support (CONFIG_KVM), with nested visualization(nVMX) feature enabled(nested=1), is vulnerable to host memory leakage issue. It could occur while emulating VMXON instruction in 'handle_vmon'. An L1 guest user could use this flaw to leak host memory potentially resulting in DoS.
