Title
tcp_bpf: fix return value of tcp_bpf_sendmsg()
Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp_bpf: fix return value of tcp_bpf_sendmsg()
When we cork messages in psock->cork, the last message triggers the
flushing will result in sending a sk_msg larger than the current
message size. In this case, in tcp_bpf_send_verdict(), 'copied' becomes
negative at least in the following case:
468 case __SK_DROP:
469 default:
470 sk_msg_free_partial(sk, msg, tosend);
471 sk_msg_apply_bytes(psock, tosend);
472 *copied -= (tosend + delta); // <==== HERE
473 return -EACCES;
Therefore, it could lead to the following BUG with a proper value of
'copied' (thanks to syzbot). We should not use negative 'copied' as a
return value here.

"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-\u003ecork, 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(), \u0027copied\u0027 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); // \u003c==== HERE\n473 return -EACCES;\n\nTherefore, it could lead to the following BUG with a proper value of\n\u0027copied\u0027 (thanks to syzbot).

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
