Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Fix resource leak in lpfc_sli4_send_seq_to_ulp()

If no handler is found in lpfc_complete_unsol_iocb() to match the rctl of a received frame, the frame is dropped and resources are leaked.

Fix by returning resources when discarding an unhandled frame type. Update lpfc_fc_frame_check() handling of NOP basic link service.
