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

Status: published. Published: 2026-08-15. Updated: 2026-11-06.

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.
