Such a packet is easily constructed. Syzbot generates them and sets off this warning. Remove the warning as it is expected and not actionable. [Fix] Noble: Clean cherry-pick from linux-6.10.y Jammy: Backport - use 'goto out_unlock' instead of 'goto out' to adjust for not including commit fc1ca3348a74a1af (gro: remove rcu_read_lock/rcu_read_unlock from gro_receive handlers) Focal: Jammy patch applied cleanly Bionic: fix sent to esm ML Xenial: fix sent to esm ML Trusty: not-affected [Test Case] Compile and boot tested. [Where problems could occur] This fix affects those who use FOU (Foo-over-UDP), an issue with this fix would be visible to the user via continued excessive warnings from 'gue_gro_recieve'.
