Fixed double free of the ha->vp_map pointer. Fixed underflow in parse_server_interfaces. Fixed Integer Overflow or Wraparound vulnerability in x86 and ARM md, raid, raid5 modules. Fixed use-after-free in ip6_route_mpath_notify. Fixed memory corruption in wifi/iwlwifi. Fixed an out-of-bound bug in ipvlan caused by unset skb->mac_header. Fixed SDMA off-by-one error in _pad_sdma_tx_descs. Fixed a race condition in nfc_llcp_sock_get and nfc_llcp_sock_get_sn.
