Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix possible memory leak when failing to issue CMF WQE There is no corresponding free routine if lpfc_sli4_issue_wqe fails to issue the CMF WQE in lpfc_issue_cmf_sync_wqe. If ret_val is non-zero, then free the iocbq request structure.
