The inbound\nsg_copy_to_buffer() only fills as many bytes as the user request payload\nprovides, and qla26xx_dport_diagnostics() zeroes only dd->buf. The\noptions and unused[] fields are therefore copied out uninitialized,\nleaking kernel heap contents to user space.\n\nAllocate with kzalloc_obj(), matching qla2x00_do_dport_diagnostics_v2()."
