Description OSIDB Bzimport 2025-06-18 12:06:37 UTC

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.
