CVE-2022-49534
5.5
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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.
