CVE-2025-40233

CVE-2025-40233 : In the Linux kernel, the OCFS2 filesystem could see stale extent flags after moving/defragmenting extents, triggering a local kernel BUG_ON in ocfs2_refcount_cal_cow_clusters. The issue arises when a reflinked extent is created via copy_file_range, and FITRIM moves extents, causi...

CVE-2023-53564

CVE-2023-53564 affects the OCFS2 defragmentation code in the Linux kernel. The vulnerability arises when ocfs2_move_extents and __ocfs2_move_extent incorrectly invoke journal access/dirty pairs (via ocfs2_journal_access_di and ocfs2_journal_dirty) during defragmentation, allowing a crash caused b...

PT-2025-40706

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contains a flaw within the OCFS2 file system related to defragmentation. A specific code path, initiated by ocfs2 ioctl move extents, leads to a call stack involving ocf...
