CVE-2014-8134  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 3.18.1 or higher.

Overview

The paravirt_ops_setup function in arch/x86/kernel/kvm.c in the Linux kernel through 3.18 uses an improper paravirt_enabled setting for KVM guest kernels, which makes it easier for guest OS users to bypass the ASLR protection mechanism via a crafted application that reads a 16-bit value.
