CVE-2026-72162

CVE-2026-72162 — In the Linux kernel OCFS2 code, a UBSAN array-index-out-of-bounds flaw occurs in ocfs2_sum_rightmost_rec when l_next_free_rec is 0 or exceeds l_count, indexing l_recs[] out of bounds. The root cause is computing i = le16_to_cpu(el->l_next_free_rec) - 1 without validating i. Th...

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...
