Summary
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.
