SOL17120: Linux kernel vulnerability CVE-2014-8134
Security Advisory
Original Publication Date: 08/13/2015
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 (CVE-2014-8134)
Impact
BIG-IP hardware platforms and Virtual Clustered Multiprocessing (vCMP) hosts
are not affected by these vulnerabilities. These vulnerabilities allow the
unauthorized disclosure of information.
Status
F5 Product Development has assigned ID 520175 (BIG-IP and Enterprise Manager)
and ID 654321 (ARX) to this vulnerability, and has evaluated the currently
supported releases for potential vulnerability.

features that are affected by the vulnerability, and for information about
releases or hotfixes that address the vulnerability, refer to the following

Severity value. Security Advisory articles published before this date do not
list a Severity value.
Recommended Action
If the previous table lists a version in the Versions known to be not
vulnerable column, you can eliminate this vulnerability by upgrading to the
listed version. If the listed version is older than the version you are
currently running, or if the table does not list any version in the column,
then no upgrade candidate currently exists.
F5 responds to vulnerabilities in accordance with the Severity values
published in the previous table. The Severity values and other security
