Like many other places, we have to check that the array index is within allowed limits, or otherwise, a kernel oops and other nastiness can ensue when we access memory beyond the end of the array. [ 5954.115381] BUG: unable to handle kernel paging request at 0000004000000000 [ 5954.120014] IP: __find_logger+0x6f/0xa0 [ 5954.123979] nf_log_bind_pf+0x2b/0x70 [ 5954.123979] nfulnl_recv_config+0xc0/0x4a0 [nfnetlink_log] [ 5954.123979] nfnetlink_rcv_msg+0x12c/0x1b0 [nfnetlink] ... The problem goes back to v2.6.30-rc1~1372~1342~31 where nf_log_bind was decoupled from nf_log_register.
