{"id":"DEBIAN-CVE-2022-49204","details":"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-\u003esg.size  //msg-\u003esg.size = 22220  case __SK_REDIRECT:   sk_msg_return()  //uncharged msg-\u003esg.size(22220) sk-\u003esk_forward_alloc   tcp_bpf_sendmsg_redir() //after tcp_bpf_sendmsg_redir, msg-\u003esg.size=11000  goto more_data;  tosend = msg-\u003esg.size  //msg-\u003esg.size = 11000  case __SK_REDIRECT:   sk_msg_return()  //uncharged msg-\u003esg.size(11000) to sk-\u003esk_forward_alloc  The msg-\u003esg.size(11000) has been uncharged twice, to fix we can charge the remaining msg-\u003esg.size before goto more data.
