An unprivileged local attacker could exploit this by getting a netlink
based service, that relies on netlink credentials, to perform privileged
actions. (CVE-2012-3520)

Mathias Krause discovered information leak in the Linux kernel's compat
ioctl interface. A local user could exploit the flaw to examine parts of
kernel stack memory (CVE-2012-6539)

Mathias Krause discovered an information leak in the Linux kernel's
getsockopt for IP_VS_SO_GET_TIMEOUT. A local user could exploit this flaw
to examine parts of kernel stack memory. (CVE-2012-6540)

Mathias Krause discovered an information leak in the Linux kernel's
getsockopt implementation for the Datagram Congestion Control Protocol
(DCCP). A local user could exploit this flaw to examine some of the
kernel's stack memory. (CVE-2012-6541)

Mathias Krause discovered an information leak in the Linux kernel's
getsockname implementation for Logical Link Layer (llc) sockets. A local
user could exploit this flaw to examine some of the kernel's stack memory.
(CVE-2012-6542)

Mathias Krause discovered information leaks in the Linux kernel's Bluetooth
Logical Link Control and Adaptation Protocol (L2CAP) implementation. A
local user could exploit these flaws to examine some of the kernel's stack
memory. (CVE-2012-6544)

Mathias Krause discovered information leaks in the Linux kernel's Bluetooth
RFCOMM protocol implementation. A local user could exploit these flaws to
examine parts of kernel memory. (CVE-2012-6545)

Mathias Krause discovered information leaks in the Linux kernel's
Asynchronous Transfer Mode (ATM) networking stack. A local user could
exploit these flaws to examine some parts of kernel memory. (CVE-2012-6546)

A flaw was discovered in how netlink sockets validate message origins. A
local attacker could exploit this flaw to send netlink message
notifications, with spoofed credentials, to subscribed tasks.
(CVE-2012-6689)

Mathias Krause discover an error in Linux kernel's Datagram Congestion
Control Protocol (DCCP) Congestion Control Identifier (CCID) use. A local
attack could exploit this flaw to cause a denial of service (crash) and
potentially escalate privileges if the user can mmap page 0.
