A vulnerability in the Linux kernel's Generic UDP Encapsulation (GUE) implementation involving the REMCSUM option has been resolved. The issue arises from an underflow in checksum offset calculations, which can lead to a buffer overflow when processing certain forwarded packets. This flaw could cause skb_copy_and_csum_dev() to write two bytes beyond the intended buffer boundary. The fix involves rejecting invalid REMCSUM offset tuples to enforce correct ordering and prevent exploitation.
