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))
