There is no fixed version for Centos:7 kernel-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-devel package and not the kernel-devel package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

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

scsi: qla2xxx: Fix a memory leak in an error path of qla2x00_process_els()

Commit 8c0eb596baa5 ("[SCSI] qla2xxx: Fix a memory leak in an error path of qla2x00_process_els()"), intended to change:

    bsg_job->request->msgcode == FC_BSG_HST_ELS_NOLOGIN


bsg_job->request->msgcode != FC_BSG_RPT_ELS

but changed it to:

    bsg_job->request->msgcode == FC_BSG_RPT_ELS

instead.

Change the == to a != to avoid leaking the fcport structure or freeing unallocated memory.
