      "title": "ocfs2: validate inline data i_size during inode read",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nocfs2: validate inline data i_size during inode read\n\nWhen reading an inode from disk, ocfs2_validate_inode_block() performs\nvarious sanity checks but does not validate the size of inline data.  If\nthe filesystem is corrupted, an inode's i_size can exceed the actual\ninline data capacity (id_count).\n\nThis causes ocfs2_dir_foreach_blk_id() to iterate beyond the inline data\nbuffer, triggering a use-after-free when accessing directory entries from\nfreed memory.\n\nIn the syzbot report:\n  - i_size was 1099511627576 bytes (~1TB)\n  - Actual inline data capacity (id_count) is typically <256 bytes\n  - A garbage rec_len (54648) caused ctx->pos to jump out of bounds\n  - This triggered a UAF in ocfs2_check_dir_entry()\n\nFix by adding a validation check in ocfs2_validate_inode_block() to ensure\ninodes with inline data have i_size <= id_count.  This catches the\ncorruption early during inode read and prevents all downstream code from\noperating on invalid data.",
