In the Linux kernel, the following vulnerability has been resolved: fou: remove warn in gue_gro_receive on unsupported protocol Drop the WARN_ON_ONCE inn gue_gro_receive if the encapsulated type is not known or does not have a GRO handler. Such a packet is easily constructed. Syzbot generates them and sets off this warning. Remove the warning as it is expected and not actionable. The warning was previously reduced from WARN_ON to WARN_ON_ONCE in commit 270136613bf7 ("fou: Do WARN_ON_ONCE in gue_gro_receive for bad proto callbacks").
