In the Linux kernel, the following vulnerability has been resolved:
idpf: fix checksums set in idpfrxrsc()
idpfrxrsc() uses skbtransportoffset(skb) while the transport header is not set yet.
This triggers the following warning for CONFIGDEBUGNET=y builds.
DEBUGNETWARNONONCE(!skbtransportheaderwasset(skb))
