Linux Linux, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6 취약점
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_D...

조치방안
제3자 참조와 수정 버전 값(5.11, 5.16, 6.1.175, 6.6.141, 6.12.91, 6.18.33, 7.0.10)은 보조 근거로만 사용하고, 공급사 공식 보안 권고에서 조치 기준을 재확인합니다.
조치 후 확인사항
패치 후 같은 명령으로 전체 버전을 다시 확인해 Linux Linux, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6 5.11, 5.16, 6.1.175, 6.6.141, 6.12.91, 6.18.33, 7.0.10 기준을 충족하는지 확인합니다. 이어서 메모리 손상 관련 오류·공격 흔적이 새로 발생하지 않는지 확인합니다.
