In the Linux kernel, the following vulnerability has been resolved: batman-adv: fix integer overflow on buff_pos Fixing an integer overflow present in batadv_iv_ogm_send_to_if. The size check is done using the int type in batadv_iv_ogm_aggr_packet whereas the buff_pos variable uses the s16 type. This could lead to an out-of-bound read.
