"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. (CVE-2014-8134)

Rabin Vincent, Robert Swiecki, Russell King discovered that the ftrace
subsystem of the Linux kernel does not properly handle private syscall
numbers. A local user could exploit this flaw to cause a denial of
service (OOPS). (CVE-2014-7826)

A flaw in the handling of malformed ASCONF chunks by SCTP (Stream
Control Transmission Protocol) implementation in the Linux kernel was
discovered. A remote attacker could exploit this flaw to cause a
denial of service (system crash). (CVE-2014-3673)

A flaw in the handling of duplicate ASCONF chunks by SCTP (Stream
Control Transmission Protocol) implementation in the Linux kernel was
discovered. A remote attacker could exploit this flaw to cause a
denial of service (panic). (CVE-2014-3687)

It was discovered that excessive queuing by SCTP (Stream Control
Transmission Protocol) implementation in the Linux kernel can cause
memory pressure. A remote attacker could exploit this flaw to cause a
denial of service. (CVE-2014-3688)

Rabin Vincent, Robert Swiecki, Russell Kinglaw discovered a flaw in
how the perf subsystem of the Linux kernel handles private systecall
numbers. A local user could exploit this to cause a denial of service
(OOPS) or bypass ASLR protections via a crafted application.
(CVE-2014-7825)

Andy Lutomirski discovered a flaw in how the Linux kernel handles
pivot_root when used with a chroot directory. A local user could
exploit this flaw to cause a denial of service (mount-tree loop).
(CVE-2014-7970)

Dmitry Monakhov discovered a race condition in the
ext4_file_write_iter function of the Linux kernel's ext4 filesystem. A
local user could exploit this flaw to cause a denial of service (file
unavailability). (CVE-2014-8086)

The KVM (kernel virtual machine) subsystem of the Linux kernel
miscalculates the number of memory pages during the handling of a
mapping failure. A guest OS user could exploit this to cause a denial
of service (host OS page unpinning) or possibly have unspecified other
impact by leveraging guest OS privileges. (CVE-2014-8369)

Andy Lutomirski discovered that the Linux kernel does not properly
handle faults associated with the Stack Segment (SS) register on the
x86 architecture. A local attacker could exploit this flaw to cause a
denial of service (panic). (CVE-2014-9090).
