Details

Dan Rosenberg discovered that IPC structures were not correctly initialized
on 64bit systems. A local attacker could exploit this to read kernel stack
memory, leading to a loss of privacy. (CVE-2010-4073)

Steve Chen discovered that setsockopt did not correctly check MSS values. A
local attacker could make a specially crafted socket call to crash the
system, leading to a denial of service. (CVE-2010-4165)

Vladymyr Denysov discovered that Xen virtual CD-ROM devices were not
handled correctly. A local attacker in a guest could make crafted blkback
requests that would crash the host, leading to a denial of service.
(CVE-2010-4238)

Vegard Nossum discovered that memory garbage collection was not handled
correctly for active sockets. A local attacker could exploit this to
allocate all available kernel memory, leading to a denial of service.
(CVE-2010-4249)

Dan Carpenter discovered that the Infiniband driver did not correctly
handle certain requests. A local user could exploit this to crash the
system or potentially gain root privileges. (CVE-2010-4649, CVE-2011-1044)

Dan Rosenberg discovered that XFS did not correctly initialize memory. A
local attacker could make crafted ioctl calls to leak portions of kernel
stack memory, leading to a loss of privacy. (CVE-2011-0711)

Timo Warns discovered that MAC 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 or potentially gain
root privileges. (CVE-2011-1010)

Neil Horman discovered that NFSv4 did not correctly handle certain orders
of operation with ACL data. A remote attacker with access to an NFSv4 mount
could exploit this to crash the system, leading to a denial of service.
(CVE-2011-1090)

Vasiliy Kulikov discovered that the netfilter code did not check certain
strings copied from userspace. A local attacker with netfilter access could
exploit this to read kernel memory or crash the system, leading to a denial
of service. (CVE-2011-1170, CVE-2011-1171, CVE-2011-1172, CVE-2011-2534)

Vasiliy Kulikov discovered that the Acorn Universal Networking driver did
not correctly initialize memory. A remote attacker could send specially
crafted traffic to read kernel stack memory, leading to a loss of privacy.
(CVE-2011-1173)

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)
