In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix memory leak in lpfc_create_port()
Commit 5e633302ace1 ("scsi: lpfc: vmid: Add support for VMID in mailbox
command") introduced allocations for the VMID resources in
lpfc_create_port() after the call to scsi_host_alloc(). Upon failure on the
VMID allocations, the new code would branch to the 'out' label, which
returns NULL without unwinding anything, thus skipping the call to
scsi_host_put().
Fix the problem by creating a separate label 'out_free_vmid' to unwind the
VMID resources and make the 'out_put_shost' label call only
scsi_host_put(), as was done before the introduction of allocations for
VMID.
