In the Linux kernel, the following vulnerability has been resolved:

idpf: fix checksums set in idpf_rx_rsc()

idpf_rx_rsc() uses skb_transport_offset(skb) while the transport header
is not set yet.

This triggers the following warning for CONFIG_DEBUG_NET=y builds.

DEBUG_NET_WARN_ON_ONCE(!skb_transport_header_was_set(skb))
