In the Linux kernel, the following vulnerability has been resolved: batman-adv: gw: acquire ethernet header 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.
