include/net/netfilter/nf_conntrack_extend.h in the netfilter subsystem in the Linux kernel before 3.14.5 uses an insufficiently large data type for certain extension data, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via outbound network traffic that triggers extension loading, as demonstrated by configuring a PPTP tunnel in a NAT environment.

CVE-2014-9715 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the kernel.
Vincent Tondellier discovered an integer overflow in the Linux kernel's
netfilter connection tracking accounting of loaded extensions. An attacker
on the local area network (LAN) could potential exploit this flaw to cause
a denial of service (system crash of targeted system). (CVE-2014-9715)
Jan Beulich discovered the Xen virtual machine subsystem of the Linux
kernel did not properly restrict access to PCI command registers. A local
guest user could exploit this flaw to cause a denial of service (host
crash). (CVE-2015-2150)
A privilege escalation was discovered in the fork syscall via the int80 entry
on 64 bit kernels with 32 bit emulation support. An unprivileged local

CVE-2014-9715 [MEDIUM] CWE-841 kernel: netfilter connection tracking extensions denial of service
kernel: netfilter connection tracking extensions denial of service
include/net/netfilter/nf_conntrack_extend.h in the netfilter subsystem in the Linux kernel before 3.14.5 uses an insufficiently large data type for certain extension data, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via outbound network traffic that triggers extension loading, as demonstrated by configuring a PPTP tunnel in a NAT environment.
An integer overflow flaw was found in the way the Linux kernel's netfilter connection tracking implementation loaded extensions. An attacker on a local network could potentially send a sequence of specially crafted packets that would initiate the loading of a large number of extensions, causing the targeted system in that network to crash
