CVE-2014-8134

Priority
High
Description
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.
Ubuntu-Description
An information leak in the Linux kernel was discovered that could leak the
high 16 bits of the kernel stack address on 32-bit Kernel Virtual Machine
(KVM) paravirt guests. A user in the guest OS could exploit this leak to
obtain information that could potentially be used to aid in attacking the
kernel.
