Impact
In the Linux kernel, the following vulnerability has been resolved: ethtool: tsinfo: don't pass ERR_PTR to genlmsg_cancel on prepare failure The goto err label leads to: genlmsg_cancel(skb, ehdr); return ret; If ethnl_tsinfo_prepare_dump() failed, it has not started a genlmsg. There's nothing to cancel, and passing an error pointer to genlmsg_cancel() would cause a crash.
