  "details": "In the Linux kernel, the following vulnerability has been resolved:  ocfs2: add journal NULL check in ocfs2_checkpoint_inode()  During unmount, ocfs2_journal_shutdown() frees the journal and sets osb-\u003ejournal to NULL. Later, when VFS evicts remaining cached inodes, ocfs2_evict_inode() -\u003e ocfs2_clear_inode() -\u003e ocfs2_checkpoint_inode() -\u003e ocfs2_ci_fully_checkpointed() dereferences osb-\u003ejournal, causing a NULL pointer dereference.  Fix this by adding a NULL check for osb-\u003ejournal in ocfs2_checkpoint_inode(). If the journal is NULL, it has already been fully flushed and destroyed during shutdown, so there is nothing to checkpoint.",
