CVE-2026-45847

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.
