CVE-2025-68191

In the Linux kernel, CVE-2025-68191 is addressed by replacing netdev_WARN() with netdev_warn() in udp_tunnel_nic_register(). The old netdev_WARN() prints a backtrace via WARN/WARN_ON, which is inappropriate for an error that is simply a normal memory-allocation failure (kzalloc() or udp_tunnel_ni...
