In the Linux kernel, the following vulnerability has been resolved:
e100: Fix possible use after free in e100xmitprepare
In e100xmitprepare(), if we can't map the skb, then return -ENOMEM, so e100xmitframe() will return NETDEVTXBUSY and the upper layer will resend the skb. But the skb is already freed, which will cause UAF bug when the upper layer resends the skb.
Remove the harmful free.
