CVE-2026-31596

CVE-2026-31596 affects OCFS2 in the Linux kernel. The vulnerability stems from ocfs2_group_extend assuming a validated global bitmap inode block from ocfs2_inode_lock(), and BUG_ON() when the signature isn’t a dinode. A crafted filesystem can bypass structural validation via the JBD2 path, leadin...

CVE-2025-68364

The CVE refers to a Linux kernel issue in the OCFS2 filesystem: in __ocfs2_move_extent(), a BUG() was relaxed to ocfs2_error() to avoid crashing the entire kernel due to filesystem corruption. This indicates the root cause was a kernel-crashing error path in ocfs2_move_extent() that could exacerb...
