Subject: [PATCH] scsi: mptsas: use g_new0 to allocate MPTSASRequest object
|
|
|
|
When processing IO request in mptsas, it uses g_new to allocate
|
|
a 'req' object. If an error occurs before 'req->sreq' is
|
|
allocated, It could lead to an OOB write in mptsas_free_request
|
|
function. Use g_new0 to avoid it.
