How to fix?

Upgrade RHEL:6 kernel-kdump to version 0:2.6.32-220.7.1.el6 or higher.
This issue was patched in RHSA-2012:0350.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-kdump package and not the kernel-kdump package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The em_syscall function in arch/x86/kvm/emulate.c in the KVM implementation in the Linux kernel before 3.2.14 does not properly handle the 0f05 (aka syscall) opcode, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application, as demonstrated by an NASM file.
