| 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. |
