CVE-2014-9715

Linux Kernel < 3.14.4 - Denial of Service via Netfilter Extension Data Type

Title source: llm
STIX 2.1

Description

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.
