Description

The KVM implementation in the Linux kernel before 2.6.36 does not properly reload the FS and GS segment registers, which allows host OS users to cause a denial of service (host OS crash) via a KVM_RUN ioctl call in conjunction with a modified Local Descriptor Table (LDT).

Solution(s)

  • redhat-upgrade-kmod-kvm
  • redhat-upgrade-kvm
  • redhat-upgrade-kvm-qemu-img
  • redhat-upgrade-kvm-tools

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
