Details

Kees Cook discovered that some ethtool functions did not correctly clear
heap memory. A local attacker with CAP_NET_ADMIN privileges could exploit
this to read portions of kernel heap memory, leading to a loss of privacy.
(CVE-2010-4655)

Kees Cook discovered that the IOWarrior USB device driver did not correctly
check certain size fields. A local attacker with physical access could plug
in a specially crafted USB device to crash the system or potentially gain
root privileges. (CVE-2010-4656)

Goldwyn Rodrigues discovered that the OCFS2 filesystem did not correctly
clear memory when writing certain file holes. A local attacker could
exploit this to read uninitialized data from the disk, leading to a loss of
privacy. (CVE-2011-0463)

Jens Kuehnel discovered that the InfiniBand driver contained a race
condition. On systems using InfiniBand, a local attacker could send
specially crafted requests to crash the system, leading to a denial of
service. (CVE-2011-0695)

Rafael Dominguez Vega discovered that the caiaq Native Instruments USB
driver did not correctly validate string lengths. A local attacker with
physical access could plug in a specially crafted USB device to crash the
system or potentially gain root privileges. (CVE-2011-0712)

Timo Warns discovered that LDM partition parsing routines did not correctly
calculate block counts. 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-2011-1012)

Timo Warns discovered that the LDM disk partition handling code did not
correctly handle certain values. By inserting a specially crafted disk
device, a local attacker could exploit this to gain root privileges.
(CVE-2011-1017)

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)
