"Dan Rosenberg discovered that multiple terminal ioctls did not
correctly initialize structure memory. A local attacker could exploit
this to read portions of kernel stack memory, leading to a loss of
privacy. (CVE-2010-4076, CVE-2010-4077)

Alex Shi and Eric Dumazet discovered that the network stack did not
correctly handle packet backlogs. A remote attacker could exploit this
by sending a large amount of network traffic to cause the system to
run out of memory, leading to a denial of service. (CVE-2010-4251,
CVE-2010-4805)

It was discovered that the /proc filesystem did not correctly handle
permission changes when programs executed. A local attacker could hold
open files to examine details about programs running with higher
privileges, potentially increasing the chances of exploiting
additional vulnerabilities. (CVE-2011-1020)

Dan Rosenberg discovered that the X.25 Rose network stack did not
correctly handle certain fields. If a system was running with Rose
enabled, a remote attacker could send specially crafted traffic to
gain root privileges. (CVE-2011-1493)

Timo Warns discovered that the GUID partition parsing routines did not
correctly validate certain structures. A local attacker with physical
access could plug in a specially crafted block device to crash the
system, leading to a denial of service. (CVE-2011-1577)

It was discovered that CIFS incorrectly handled authentication. When a
user had a CIFS share mounted that required authentication, a local
user could mount the same share without knowing the correct password.
(CVE-2011-1585)

It was discovered that the GRE protocol incorrectly handled netns
initialization. A remote attacker could send a packet while the ip_gre
module was loading, and crash the system, leading to a denial of
service. (CVE-2011-1767)

It was discovered that the IP/IP protocol incorrectly handled netns
initialization. A remote attacker could send a packet while the ipip
module was loading, and crash the system, leading to a denial of
service. (CVE-2011-1768)

Ben Hutchings reported a flaw in the kernel's handling of corrupt LDM
partitions. A local user could exploit this to cause a denial of
service or escalate privileges. (CVE-2011-2182)

Andrea Righi discovered a race condition in the KSM memory merging
support. If KSM was being used, a local attacker could exploit this to
crash the system, leading to a denial of service. (CVE-2011-2183)

Dan Rosenberg discovered that the IPv4 diagnostic routines did not
correctly validate certain requests. A local attacker could exploit
this to consume CPU resources, leading to a denial of service.
(CVE-2011-2213)

Vasiliy Kulikov discovered that taskstats listeners were not correctly
handled. A local attacker could expoit this to exhaust memory and CPU
resources, leading to a denial of service. (CVE-2011-2484)

It was discovered that Bluetooth l2cap and rfcomm did not correctly
initialize structures. A local attacker could exploit this to read
portions of the kernel stack, leading to a loss of privacy.
(CVE-2011-2492)

Mauro Carvalho Chehab discovered that the si4713 radio driver did not
correctly check the length of memory copies. If this hardware was
available, a local attacker could exploit this to crash the system or
gain root privileges. (CVE-2011-2700)

Herbert Xu discovered that certain fields were incorrectly handled
when Generic Receive Offload (CVE-2011-2723)

Vasiliy Kulikov discovered that the Comedi driver did not correctly
clear memory. A local attacker could exploit this to read kernel stack
memory, leading to a loss of privacy. (CVE-2011-2909)

The performance counter subsystem did not correctly handle certain
counters. A local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2011-2918)

A flaw was found in the Linux kernel's /proc/*/*map* interface. A
local, unprivileged user could exploit this flaw to cause a denial of
service. (CVE-2011-3637)

Ben Hutchings discovered several flaws in the Linux Rose (X.25 PLP)
layer. A local user or a remote user on an X.25 network could exploit
these flaws to execute arbitrary code as root. (CVE-2011-4914)."
