      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nocfs2: validate DIO orphan slot during inode read\n\n[BUG]\nA corrupted append-DIO dinode (high byte at offset 0xa1\ncorrupted from 0 to 1) can carry an i_dio_orphaned_slot\noutside the mounted filesystem slot range and trigger a\nuse-after-free error:\n\nBUG: KASAN: slab-use-after-free in ocfs2_get_system_file_inode+0x780/0x820 fs/ocfs2/sysfile.c:102\nRead of size 8 at addr ffff88800b767c00 by task kworker/u8:3/85\nCall Trace:\n ...\n ocfs2_get_system_file_inode+0x780/0x820 fs/ocfs2/sysfile.c:102\n ocfs2_wipe_inode+0x292/0xf70 fs/ocfs2/inode.c:840\n ocfs2_delete_inode fs/ocfs2/inode.c:1155 [inline]\n ocfs2_evict_inode+0x6c9/0x1170 fs/ocfs2/inode.c:1295\n evict+0x38e/0x8f0 fs/inode.c:810\n iput_final fs/inode.c:1914 [inline]\n iput fs/inode.c:1966 [inline]\n iput+0x55b/0x8b0 fs/inode.c:1926\n ocfs2_recover_orphans+0x610/0xe40 fs/ocfs2/journal.c:2374\n ocfs2_complete_recovery+0x5af/0xd00 fs/ocfs2/journal.c:1373\n ...\n\n[CAUSE]\nocfs2_del_inode_from_orphan() uses i_dio_orphaned_slot to index the\nslot-local system inode cache. The dinode validator does not check\nthis active slot, so an out-of-range value produces an invalid cache\nentry pointer that is dereferenced as an inode pointer.\n\n[FIX]\nReject an active i_dio_orphaned_slot outside the slot range during\ndinode validation, before DIO orphan recovery can consume it.",
