Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
net: remove WARN_ON_ONCE when accessing forward path array<br />
<br />
Although unlikely, recent support for IPIP tunnels increases chances of<br />
reaching this WARN_ON_ONCE if userspace manages to build a sufficiently<br />
long forward path.<br />
<br />
Remove it.
