In the Linux kernel, the following vulnerability has been resolved:

net: remove WARN_ON_ONCE when accessing forward path array

Although unlikely, recent support for IPIP tunnels increases chances of
reaching this WARN_ON_ONCE if userspace manages to build a sufficiently
long forward path.

Remove it.
