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

scsi: lpfc: Resolve NULL ptr dereference after an ELS LOGO is aborted

A use-after-free crash can occur after an ELS LOGO is aborted.

Specifically, a nodelist structure is freed and then ndlp->vport->cfg_log_verbose is dereferenced in lpfc_nlp_get() when the discovery state machine is mistakenly called a second time with NLP_EVT_DEVICE_RM argument.

Rework lpfc_cmpl_els_logo() to prevent the duplicate calls to release a nodelist structure.
