Julien Tinnes discovered that the kernel did not correctly validate
the signal structure from tkill(). A local attacker could exploit
this to send signals to arbitrary threads, possibly bypassing
expected restrictions. (CVE-2011-1182)

Ryan Sweat discovered that the GRO code did not correctly validate
memory. In some configurations on systems using VLANs, a remote
attacker could send specially crafted traffic to crash the system,
leading to a denial of service. (CVE-2011-1478)

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)

Dan Rosenberg discovered that MPT devices did not correctly validate
certain values in ioctl calls. If these drivers were loaded, a local
attacker could exploit this to read arbitrary kernel memory, leading
to a loss of privacy. (CVE-2011-1494, CVE-2011-1495)

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)

Tavis Ormandy discovered that the pidmap function did not correctly
handle large requests. A local attacker could exploit this to crash
the system, leading to a denial of service. (CVE-2011-1593)

Oliver Hartkopp and Dave Jones discovered that the CAN network driver
did not correctly validate certain socket structures. If this driver
was loaded, a local attacker could crash the system, leading to a
denial of service. (CVE-2011-1598, CVE-2011-1748)

Vasiliy Kulikov discovered that the AGP driver did not check certain
ioctl values. A local attacker with access to the video subsystem
could exploit this to crash the system, leading to a denial of
service, or possibly gain root privileges. (CVE-2011-1745,
CVE-2011-2022)

Vasiliy Kulikov discovered that the AGP driver did not check the size
of certain memory allocations. A local attacker with access to the
video subsystem could exploit this to run the system out of memory,
leading to a denial of service. (CVE-2011-1746)

Dan Rosenberg discovered that the DCCP stack did not correctly handle
certain packet structures. A remote attacker could exploit this to
crash the system, leading to a denial of service. (CVE-2011-1770)

Vasiliy Kulikov and Dan Rosenberg discovered that ecryptfs did not
correctly check the origin of mount points. A local attacker could
exploit this to trick the system into unmounting arbitrary mount
points, leading to a denial of service. (CVE-2011-1833)

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)

Fernando Gont discovered that the IPv6 stack used predictable
fragment identification numbers. A remote attacker could exploit this
to exhaust network resources, leading to a denial of service.
(CVE-2011-2699)

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)");
