Description

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)

It was discovered that an mmap() call with the MAP_PRIVATE flag on
‘/dev/zero’ was incorrectly handled. A local attacker could exploit
this to crash the system, leading to a denial of service.
(CVE-2011-2479)

Vasily Averin discovered that the NFS Lock Manager (NLM) incorrectly
handled unlock requests. A local attacker could exploit this to cause
a denial of service. (CVE-2011-2491)

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)

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)

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)

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)
