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. (NVD)
