CVE-2026-72162 ocfs2: fix UBSAN array-index-out-of-bounds in ocfs2_sum_rightmost_rec

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix UBSAN array-index-out-of-bounds in ocfs2sumrightmostrec BUG On-disk corruption setting lnextfreerec to 0 in an inode's embedded extent list triggers a UBSAN panic on the next write to that file. CAUSE...

CVE-2026-72162

CVE-2026-72162 affects the Linux kernel OCFS2 subsystem. A UBSAN array-index-out-of-bounds can occur in ocfs2_sum_rightmost_rec when l_next_free_rec is 0 or exceeds l_count, indexing l_recs[] out of bounds. The fix validates the inode’s embedded extent list on read via ocfs2_validate_inode_block:...

CVE-2026-72161 ocfs2: add journal NULL check in ocfs2_checkpoint_inode()

In the Linux kernel, the following vulnerability has been resolved: ocfs2: add journal NULL check in ocfs2checkpointinode During unmount, ocfs2journalshutdown frees the journal and sets osb-journal to NULL. Later, when VFS evicts remaining cached inodes, ocfs2evictinode - ocfs2clearinode -...

CVE-2026-72161

The CVE describes a NULL dereference in OCFS2 during inode eviction after unmount, caused by osb->journal being freed but later dereferenced in ocfs2_checkpoint_inode(). The fix adds a NULL check for osb->journal in ocfs2_checkpoint_inode(), so if the journal is NULL (already flushed/destro...
