CVE-2022-49534 Information

Description

In the Linux kernel the following vulnerability has been resolved:

scsi: lpfc: Protect memory leak for NPIV ports sending PLOGI_RJT

There is a potential memory leak in lpfc_ignore_els_cmpl() and lpfc_els_rsp_reject() that was allocated from NPIV PLOGI_RJT (lpfc_rcv_plogi()’s login_mbox).

Check if cmdiocb->context_un.mbox was allocated in lpfc_ignore_els_cmpl() and then free it back to phba->mbox_mem_pool along with mbox->ctx_buf for service parameters.

For lpfc_els_rsp_reject() failure free both the ctx_buf for service parameters and the login_mbox.
