Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.14.5

Description The issue is related to the netfilter subsystem in the Linux kernel, where an insufficiently large data type is used for certain extension data. This can be exploited by local users to cause a denial of service, resulting in a NULL pointer dereference and OOPS, via outbound network traffic that triggers extension loading. An example of how this can be triggered is by configuring a PPTP tunnel in a NAT environment.

Recommendations For Linux kernel versions prior to 3.14.5, update to version 3.14.5 or later to resolve the issue. As a temporary workaround, consider restricting outbound network traffic to minimize the risk of exploitation.
