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.
