Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> tcp_bpf: fix return value of tcp_bpf_sendmsg()<br /> <br /> When we cork messages in psock-&gt;cork, the last message triggers the<br /> flushing will result in sending a sk_msg larger than the current<br /> message size. In this case, in tcp_bpf_send_verdict(), &amp;#39;copied&amp;#39; becomes<br /> negative at least in the following case:<br /> <br /> 468 case __SK_DROP:<br /> 469 default:<br /> 470 sk_msg_free_partial(sk, msg, tosend);<br /> 471 sk_msg_apply_bytes(psock, tosend);<br /> 472 *copied -= (tosend + delta); //
