In the Linux kernel, the following vulnerability has been resolved:

batman-adv: retrieve ethhdr after potential skb realloc on RX

pskb_may_pull() in batadv_interface_rx() 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 VLAN header but missed for the ethernet

header which is later used for the TT and AP isolation handling. (NVD)
