Descriptions

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

scsi: lpfc: Fix possible memory leak in lpfc_rcv_padisc()

The call to lpfc_sli4_resume_rpi() in lpfc_rcv_padisc() may return an
unsuccessful status. In such cases, the elsiocb is not issued, the
completion is not called, and thus the elsiocb resource is leaked.

Check return value after calling lpfc_sli4_resume_rpi() and conditionally
release the elsiocb resource.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: scsi: lpfc: corrige una posible pérdida de memoria en lpfc_rcv_padisc() La llamada a lpfc_sli4_resume_rpi() en lpfc_rcv_padisc() puede devolver un estado fallido. En tales casos, no se emite elsiocb, no se llama a la finalización y, por lo tanto, se filtra el recurso elsiocb. Verifique el valor de retorno después de llamar a lpfc_sli4_resume_rpi() y libere condicionalmente el recurso elsiocb.
