"It was discovered that the Stream Control Transmission Protocol
(SCTP) implementation incorrectly calculated lengths. If the
net.sctp.addip_enable variable was turned on, a remote attacker could
send specially crafted traffic to crash the system. (CVE-2011-1573)

Ryan Sweat discovered that the kernel incorrectly handled certain
VLAN packets. On some systems, a remote attacker could send specially
crafted traffic to crash the system, leading to a denial of service.
(CVE-2011-1576)

Timo Warns discovered that the EFI GUID partition table was not
correctly parsed. A physically local attacker that could insert
mountable devices could exploit this to crash the system or possibly
gain root privileges. (CVE-2011-1776)

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 did not enforce access
restrictions. A local attacker could exploit this to read certain
information, leading to a loss of privacy. (CVE-2011-2494)

Vasiliy Kulikov discovered that /proc/PID/io did not enforce access
restrictions. A local attacker could exploit this to read certain
information, leading to a loss of privacy. (CVE-2011-2495)

Robert Swiecki discovered that mapping extensions were incorrectly
handled. A local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2011-2496)

Dan Rosenberg discovered that the Bluetooth stack incorrectly handled
certain L2CAP requests. If a system was using Bluetooth, a remote
attacker could send specially crafted traffic to crash the system or
gain root privileges. (CVE-2011-2497)

It was discovered that the wireless stack incorrectly verified SSID
lengths. A local attacker could exploit this to cause a denial of
service or gain root privileges. (CVE-2011-2517)

Ben Pfaff discovered that Classless Queuing Disciplines (qdiscs) were
being incorrectly handled. A local attacker could exploit this to
crash the system, leading to a denial of service. (CVE-2011-2525)

It was discovered that the EXT4 filesystem contained multiple
off-by-one flaws. A local attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2011-2695)

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

Christian Ohm discovered that the perf command looks for
configuration files in the current directory. If a privileged user
were tricked into running perf in a directory containing a malicious
configuration file, an attacker could run arbitrary commands and
possibly gain privileges. (CVE-2011-2905)

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)

Time Warns discovered that long symlinks were incorrectly handled on
Be filesystems. A local attacker could exploit this with a malformed
Be filesystem and crash the system, leading to a denial of service.
(CVE-2011-2928)

Dan Kaminsky discovered that the kernel incorrectly handled random
sequence number generation. An attacker could use this flaw to
possibly predict sequence numbers and inject packets. (CVE-2011-3188)

Darren Lavender discovered that the CIFS client incorrectly handled
certain large values. A remote attacker with a malicious server could
exploit this to crash the system or possibly execute arbitrary code
as the root user. (CVE-2011-3191)

Yogesh Sharma discovered that CIFS did not correctly handle UNCs that
had no prefixpaths. A local attacker with access to a CIFS partition
could exploit this to crash the system, leading to a denial of
service. (CVE-2011-3363)");
