Description
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.
