Description

In the Linux kernel, the following vulnerability has been resolved:  batman-adv: dat: handle forward allocation error  batadv_dat_forward_data() calls pskb_copy_for_clone() to duplicate an skb for each DHT candidate, but does not check the return value before passing it to batadv_send_skb_prepare_unicast_4addr(). That function dereferences the skb unconditionally, so a failed allocation triggers a NULL pointer dereference.  Skip forwarding to the current DHT candidate on allocation failure.
