In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix more uncharged while msg has more_data In tcp_bpf_send_verdict(), if msg has more data after tcp_bpf_sendmsg_redir(): tcp_bpf_send_verdict() tosend = msg->sg.size //msg->sg.size = 22220 case __SK_REDIRECT: sk_msg_return() //uncharged msg->sg.size(22220) sk->sk_forward_alloc tcp_bpf_sendmsg_redir() //after tcp_bpf_sendmsg_redir, msg->sg.size=11000 goto more_data; tosend = msg->sg.size //msg->sg.size = 11000 case __SK_REDIRECT: sk_msg_return() //uncharged msg->sg.size(11000) to sk->sk_forward_alloc The msg->sg.size(11000) has been uncharged twice, to fix we can charge the remaining msg->sg.size before goto more data.
