The KVM implementation in the Linux kernel through 4.20.5 has an
Information Leak.
Author | Note |
---|---|
tyhicks | Ubuntu kernels do not enable nested KVM virtualization by default and are unaffected by this flaw in the default configuration. However, installing QEMU results in nested KVM support to be enabled via the /etc/modprobe.d/qemu-system-x86.conf file. To ensure that nested virtualization is not enabled, verify that the /sys/module/kvm_intel/parameters/nested file contains “N”. |
