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.
