CVE-2026-72087: scsi: lpfc: Fix memory leak in lpfc_sli4_driver_resource_setup()

From: Greg Kroah-Hartman <[email protected]>

Description
===========

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

scsi: lpfc: Fix memory leak in lpfc_sli4_driver_resource_setup()

The memory allocated for mboxq using mempool_alloc() is not freed in
some of the early exit error paths. Fix that by moving the
mempool_free() call to an earlier point after last use.

The Linux kernel CVE team has assigned CVE-2026-72087 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
