      "title": "ocfs2: fix out-of-bounds write in ocfs2_write_end_inline",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nocfs2: fix out-of-bounds write in ocfs2_write_end_inline\n\nKASAN reports a use-after-free write of 4086 bytes in\nocfs2_write_end_inline, called from ocfs2_write_end_nolock during a\ncopy_file_range splice fallback on a corrupted ocfs2 filesystem mounted on\na loop device.  The actual bug is an out-of-bounds write past the inode\nblock buffer, not a true use-after-free.  The write overflows into an\nadjacent freed page, which KASAN reports as UAF.\n\nThe root cause is that ocfs2_try_to_write_inline_data trusts the on-disk\nid_count field to determine whether a write fits in inline data.  On a\ncorrupted filesystem, id_count can exceed the physical maximum inline data\ncapacity, causing writes to overflow the inode block buffer.\n\nCall trace (crash path):\n\n   vfs_copy_file_range (fs/read_write.c:1634)\n     do_splice_direct\n       splice_direct_to_actor\n         iter_file_splice_write\n           ocfs2_file_write_iter\n             generic_perform_write\n               ocfs2_write_end\n                 ocfs2_write_end_nolock (fs/ocfs2/aops.c:1949)\n                   ocfs2_write_end_inline (fs/ocfs2/aops.c:1915)\n                     memcpy_from_folio     <-- KASAN: write OOB\n\nSo add id_count upper bound check in ocfs2_validate_inode_block() to\nalongside the existing i_size check to fix it.",
