Subject: [PATCH] scsi: megasas: initialise local configuration data buffer
|
|
|
|
When reading MegaRAID SAS controller configuration via MegaRAID
|
|
Firmware Interface(MFI) commands, routine megasas_dcmd_cfg_read
|
|
uses an uninitialised local data buffer. Initialise this buffer
|
|
to avoid stack information leakage.
