In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: reacquire gw address after skb realloc The pskb_may_pull() called by batadv_bla_is_backbone_gw() 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.
