The user space client doesn't have this issue because it will always skip the extra memory when decoding in DECODE_FINISHE(), please see Line#1514 below:
1503 /**
1504 * finish decode block
1505 *
1506 * @param bl bufferlist::iterator we were decoding from
1507 */
1508 #define DECODE_FINISH(bl) \
1509 } while (false); \
1510 if (struct_end) { \
1511 if (bl.get_off() > struct_end) \
1512 throw ::ceph::buffer::malformed_input(DECODE_ERR_PAST(__PRETTY_FUNCTION__)); \
1513 if (bl.get_off() < struct_end) \
1514 bl += struct_end - bl.get_off(); \
1515 }
