In the Linux kernel, the following vulnerability has been resolved:
batman-adv: access unicast_ttvn skb->data only after skb realloc
The pskb_may_pull() called by batadv_get_vid() could reallocate the buffer
behind the skb. Variables which were pointing to the old buffer need to be
reassigned to avoid an use-after-free.
This was done correctly for the ethernet header but missed for the
unicast_packet pointer.
