unprivileged user could exploit this flaw to read kernel stack memory.
(CVE-2012-0957)
Rodrigo Freire discovered a flaw in the Linux kernel's TCP illinois
congestion control algorithm. A local attacker could use this to cause a
denial of service. (CVE-2012-4565)
Mathias Krause discovered a flaw in the Linux kernel's XFRM netlink
interface. A local user with the NET_ADMIN capability could exploit this
flaw to leak the contents of kernel memory. (CVE-2012-6536)
Mathias Krause discovered several errors in the Linux kernel's xfrm_user
implementation. A local attacker could exploit these flaws to examine parts
of kernel memory. (CVE-2012-6537)
Mathias Krause discovered an information leak in the Linux kernel's
xfrm_user copy_to_user_auth function. A local user could exploit this flaw
to examine parts of kernel heap memory. (CVE-2012-6538)
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 the Linux kernels handling of memory ranges with
PROT_NONE when transparent hugepages are in use. An unprivileged local user
could exploit this flaw to cause a denial of service (crash the system).
(CVE-2013-0309)
Mathias Krause discovered a flaw in xfrm_user in the Linux kernel. A local
attacker with NET_ADMIN capability could potentially exploit this flaw to
escalate privileges. (CVE-2013-1826)
