Details

Gleb Napatov discovered that KVM did not correctly check certain privileged
operations. A local attacker with access to a guest kernel could exploit
this to crash the host system, leading to a denial of service.
(CVE-2010-0435)

Dan Jacobson discovered that ThinkPad video output was not correctly access
controlled. A local attacker could exploit this to hang the system, leading
to a denial of service. (CVE-2010-3448)

It was discovered that KVM did not correctly initialize certain CPU
registers. A local attacker could exploit this to crash the system, leading
to a denial of service. (CVE-2010-3698)

Dan Rosenberg discovered that the Linux kernel TIPC implementation
contained multiple integer signedness errors. A local attacker could
exploit this to gain root privileges. (CVE-2010-3859)

Thomas Pollet discovered that the RDS network protocol did not
check certain iovec buffers. A local attacker could exploit this
to crash the system or possibly execute arbitrary code as the root
user. (CVE-2010-3865)

Dan Rosenberg discovered that the Linux kernel X.25 implementation
incorrectly parsed facilities. A remote attacker could exploit this to
crash the kernel, leading to a denial of service. (CVE-2010-3873)

Dan Rosenberg discovered that the CAN protocol on 64bit systems did not
correctly calculate the size of certain buffers. A local attacker could
exploit this to crash the system or possibly execute arbitrary code as
the root user. (CVE-2010-3874)

Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did
not correctly clear kernel memory. A local attacker could exploit this to
read kernel stack memory, leading to a loss of privacy. (CVE-2010-3875)

Vasiliy Kulikov discovered that the Linux kernel sockets implementation did
not properly initialize certain structures. A local attacker could exploit
this to read kernel stack memory, leading to a loss of privacy.
(CVE-2010-3876)

Vasiliy Kulikov discovered that the TIPC interface did not correctly
initialize certain structures. A local attacker could exploit this to read
kernel stack memory, leading to a loss of privacy. (CVE-2010-3877)

Nelson Elhage discovered that the Linux kernel IPv4 implementation did not
properly audit certain bytecodes in netlink messages. A local attacker
could exploit this to cause the kernel to hang, leading to a denial of
service. (CVE-2010-3880)

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)

Dan Rosenberg discovered that the USB subsystem did not correctly
initialize certian structures. A local attacker could exploit this to read
kernel stack memory, leading to a loss of privacy. (CVE-2010-4074)

Dan Rosenberg discovered that the SiS video driver did not correctly clear
kernel memory. A local attacker could exploit this to read kernel stack
memory, leading to a loss of privacy. (CVE-2010-4078)

Dan Rosenberg discovered that the ivtv V4L driver did not correctly
initialize certian structures. A local attacker could exploit this to read
kernel stack memory, leading to a loss of privacy. (CVE-2010-4079)

Dan Rosenberg discovered that the RME Hammerfall DSP audio interface driver
did not correctly clear kernel memory. A local attacker could exploit this
to read kernel stack memory, leading to a loss of privacy. (CVE-2010-4080,
CVE-2010-4081)

Dan Rosenberg discovered that the VIA video driver did not correctly
clear kernel memory. A local attacker could exploit this to read kernel
stack memory, leading to a loss of privacy. (CVE-2010-4082)

Dan Rosenberg discovered that the semctl syscall did not correctly clear
kernel memory. A local attacker could exploit this to read kernel stack
memory, leading to a loss of privacy. (CVE-2010-4083)

James Bottomley discovered that the ICP vortex storage array controller
driver did not validate certain sizes. A local attacker on a 64bit system
could exploit this to crash the kernel, leading to a denial of service.
(CVE-2010-4157)

Dan Rosenberg discovered that the Linux kernel L2TP implementation
contained multiple integer signedness errors. A local attacker could
exploit this to to crash the kernel, or possibly gain root privileges.
(CVE-2010-4160)

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)

Dave Jones discovered that the mprotect system call did not correctly
handle merged VMAs. A local attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2010-4169)

It was discovered that multithreaded exec did not handle CPU timers
correctly. A local attacker could exploit this to crash the system, leading
to a denial of service. (CVE-2010-4248)

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)
