In Section 5.1, Figure 6 - TCP IPv6 Pseudoheader

+--------+--------+--------+--------+
|                                   |
+                                   +
|                                   |
+          Source Address           +
|                                   |
+                                   +
|                                   |

|                                   |
+        Destination Address        +
|                                   |

|      Upper-Layer Payload Length   |
+--------+--------+--------+--------+
|      Zero       |    Next Header  |

It should say:

+--------+--------+--------+--------+
|                                   |
+                                   +
|                                   |
+          Source Address           +
|                                   |
+                                   +
|                                   |
+                                   +
+--------+--------+--------+--------+
|                                   |
+                                   +
|                                   |
+        Destination Address        +
|                                   |
+                                   +
|                                   |
+--------+--------+--------+--------+
|      Upper-Layer Payload Length   |
+--------+--------+--------+--------+
|            Zero          |Next Hdr|
+--------+--------+--------+--------+

Notes:

In IPv6 pseudoheader, Zero field should be 3 bytes and Next header should be 1 byte.
But in RFC 5925, figure 6, it misleads into Zero field 2 bytes and Next header 2 bytes.
