"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntcp_bpf: fix return value of tcp_bpf_sendmsg()\n\nWhen we cork messages in psock->cork, the last message triggers the\nflushing will result in sending a sk_msg larger than the current\nmessage size. In this case, in tcp_bpf_send_verdict(), 'copied' becomes\nnegative at least in the following case:\n\n468 case __SK_DROP:\n469 default:\n470 sk_msg_free_partial(sk, msg, tosend);\n471 sk_msg_apply_bytes(psock, tosend);\n472 *copied -= (tosend + delta); // <==== HERE\n473 return -EACCES;\n\nTherefore, it could lead to the following BUG with a proper value of\n'copied' (thanks to syzbot).
