"An information leak was discovered in the Linux kernel when inotify is
used to monitor the /dev/ptmx device. A local user could exploit this
flaw to discover keystroke timing and potentially discover sensitive
information like password length. (CVE-2013-0160)

An information leak was discovered in the Linux kernel's tkill and
tgkill system calls when used from compat processes. A local user
could exploit this flaw to examine potentially sensitive kernel
memory. (CVE-2013-2141)

A flaw was discovered in the Linux kernel's perf events subsystem for
Intel Sandy Bridge and Ivy Bridge processors. A local user could
exploit this flaw to cause a denial of service (system crash).
(CVE-2013-2146)

An information leak was discovered in the Linux kernel's crypto API. A
local user could exploit this flaw to examine potentially sensitive
information from the kernel's stack memory. (CVE-2013-3076)

An information leak was discovered in the Linux kernel's rcvmsg path
for ATM (Asynchronous Transfer Mode). A local user could exploit this
flaw to examine potentially sensitive information from the kernel's
stack memory. (CVE-2013-3222)

An information leak was discovered in the Linux kernel's recvmsg path
for ax25 address family. A local user could exploit this flaw to
examine potentially sensitive information from the kernel's stack
memory. (CVE-2013-3223)

An information leak was discovered in the Linux kernel's recvmsg path
for the bluetooth address family. A local user could exploit this flaw
to examine potentially sensitive information from the kernel's stack
memory. (CVE-2013-3224)

An information leak was discovered in the Linux kernel's bluetooth
rfcomm protocol support. A local user could exploit this flaw to
examine potentially sensitive information from the kernel's stack
memory. (CVE-2013-3225)

An information leak was discovered in the Linux kernel's CAIF protocol
implementation. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3227)

An information leak was discovered in the Linux kernel's IRDA
(infrared) support subsystem. A local user could exploit this flaw to
examine potentially sensitive information from the kernel's stack
memory. (CVE-2013-3228)

An information leak was discovered in the Linux kernel's s390 - z/VM
support. A local user could exploit this flaw to examine potentially
sensitive information from the kernel's stack memory. (CVE-2013-3229)

An information leak was discovered in the Linux kernel's l2tp (Layer
Two Tunneling Protocol) implementation. A local user could exploit
this flaw to examine potentially sensitive information from the
kernel's stack memory. (CVE-2013-3230)

An information leak was discovered in the Linux kernel's llc (Logical
Link Layer 2) support. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3231)

An information leak was discovered in the Linux kernel's receive
message handling for the netrom address family. A local user could
exploit this flaw to obtain sensitive information from the kernel's
stack memory. (CVE-2013-3232)

An information leak was discovered in the Linux kernel's nfc (near
field communication) support. A local user could exploit this flaw to
examine potentially sensitive information from the kernel's stack
memory. (CVE-2013-3233)

An information leak was discovered in the Linux kernel's Rose X.25
protocol layer. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3234)

An information leak was discovered in the Linux kernel's TIPC
(Transparent Inter Process Communication) protocol implementation. A
local user could exploit this flaw to examine potentially sensitive
information from the kernel's stack memory. (CVE-2013-3235).
