Not Vulnerable:

Linux Kernel 'IP GRE' Module NULL Pointer Dereference Denial of Service Vulnerability

The Linux kernel is prone to a denial-of-service vulnerability.

Attackers can exploit this issue to cause the kernel to panic, denying service to legitimate users. Due to the nature of this issue, attackers may be able to execute arbitrary code; however, this has not been confirmed.

Linux Kernel 'IP GRE' Module NULL Pointer Dereference Denial of Service Vulnerability

Attackers can exploit this issue with readily available tools.

Linux Kernel 'IP GRE' Module NULL Pointer Dereference Denial of Service Vulnerability

Solution:
Updates are available. Please see the references for more information.
