## Overview

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

scsi: target: Reset t_task_cdb pointer in error case

If allocation of cmd->t_task_cdb fails, it remains NULL but is later
dereferenced in the 'err' path.

In case of error, reset NULL t_task_cdb value to point at the default
fixed-size buffer.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
