(CVE-2013-1798)

An information leak was discovered in the Linux kernel's rcvmsg path for
ATM (Asynchronous Transfer Mode). A local user could exploit this flaw to
examine potentially sensitive information from the kernel's stack memory.
(CVE-2013-3222)

An information leak was discovered in the Linux kernel's recvmsg path for
ax25 address family. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3223)

An information leak was discovered in the Linux kernel's recvmsg path for
the bluetooth address family. A local user could exploit this flaw to
examine potentially sensitive information from the kernel's stack memory.
(CVE-2013-3224)

An information leak was discovered in the Linux kernel's bluetooth rfcomm
protocol support. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3225)

An information leak was discovered in the Linux kernel's IRDA (infrared)
support subsystem. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3228)

An information leak was discovered in the Linux kernel's s390 - z/VM
support. A local user could exploit this flaw to examine potentially
sensitive information from the kernel's stack memory. (CVE-2013-3229)

An information leak was discovered in the Linux kernel's llc (Logical Link
Layer 2) support. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3231)

An information leak was discovered in the Linux kernel's receive message
handling for the netrom address family. A local user could exploit this
flaw to obtain sensitive information from the kernel's stack memory.
(CVE-2013-3232)

An information leak was discovered in the Linux kernel's Rose X.25 protocol
layer. A local user could exploit this flaw to examine potentially
sensitive information from the kernel's stack memory. (CVE-2013-3234)

An information leak was discovered in the Linux kernel's TIPC (Transparent
Inter Process Communication) protocol implementation. A local user could
exploit this flaw to examine potentially sensitive information from the
kernel's stack memory. (CVE-2013-3235)");
