Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
batman-adv: dat: acquire ARP hw source only after skb realloc<br />
<br />
The pskb_may_pull() called by batadv_get_vid() could reallocate the buffer<br />
behind the skb. Variables which were pointing to the old buffer need to be<br />
reassigned to avoid an use-after-free.
