The accidental access to a lowcore area results in a random next-hop address in the qeth_hdr. rtable (or more precisely, skb_dst(skb)) can be NULL in rare cases (for instance together with AF_PACKET sockets). Solution: Add the missing NULL-ptr checks. Reproduction: AF_PACKET program sending raw data Upstream Commit: ec2c6726322f0d270bab477e4904bf9496f70ee5 kernel 4.13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1750813/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
