Description

In the Linux kernel, the following vulnerability has been resolved: e100: Fix possible use after free in e100_xmit_prepare In e100_xmit_prepare(), if we can't map the skb, then return -ENOMEM, so e100_xmit_frame() will return NETDEV_TX_BUSY 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.

Affected configurations

• linux linux kernel (>= 4.3 < 5.10.158) • linux linux kernel (>= 5.11 < 5.15.82) • linux linux kernel (>= 5.16 < 6.0.12) • linux linux kernel 6.1
