In the Linux kernel, the following vulnerability has been resolved: net: dlink: handle copy_thresh allocation failure The driver did not handle failure of netdev_alloc_skb_ip_align(). If the allocation failed, dereferencing skb->protocol could lead to a NULL pointer dereference. This patch tries to allocate skb. If the allocation fails, it falls back to the normal path. Tested-on: D-Link DGE-550T Rev-A3
