Title
scsi: lpfc: Fix resource leak in lpfc_sli4_send_seq_to_ulp()
Summary
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.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
