| Doc Text: |
A NULL pointer dereference vulnerability wqas found in the ocfs2_journal_dirty() function in the Linux kernel's OCFS2 file system. This issue arose after a code change in commit 8887b94d9322, which replaced bdev->bd_super with b_assoc_map->host->i_sb, but failed to initialize b_assoc_map. Consequently, the function would crash if b_assoc_map was NULL.
