Summary
ext4: update s_journal_inum if it changes after journal replay
Details

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

ext4: update sjournalinum if it changes after journal replay

When mounting a crafted ext4 image, sjournalinum may change after journal replay, which is obviously unreasonable because we have successfully loaded and replayed the journal through the old sjournalinum. And the new sjournalinum bypasses some of the checks in ext4getjournal(), which may trigger a null pointer dereference problem. So if sjournalinum changes after the journal replay, we ignore the change, and rewrite the current journal_inum to the superblock.
