- Summary
- nvmet-tcp: propagate nvmet_tcp_build_pdu_iovec() errors to its callers
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
nvmet-tcp: propagate nvmet_tcp_build_pdu_iovec() errors to its callers
Currently, when nvmet_tcp_build_pdu_iovec() detects an out-of-bounds PDU length or offset, it triggers nvmet_tcp_fatal_error(cmd->queue) and returns early. However, because the function returns void, the callers are entirely unaware that a fatal error has occurred and that the cmd->recv_msg.msg_iter was left uninitialized.
Callers such as nvmet_tcp_handle_h2c_data_pdu() proceed to blindly overwrite the queue state with queue->rcv_state = NVMET_TCP_RECV_DATA Consequently, the socket receiving loop may attempt to read incoming network data into the uninitialized iterator.
Fix this by shifting the error handling responsibility to the callers.
