  "details": "In the Linux kernel, the following vulnerability has been resolved:  ocfs2: validate DIO orphan slot during inode read  [BUG] A corrupted append-DIO dinode (high byte at offset 0xa1 corrupted from 0 to 1) can carry an i_dio_orphaned_slot outside the mounted filesystem slot range and trigger a use-after-free error:  BUG: KASAN: slab-use-after-free in ocfs2_get_system_file_inode+0x780/0x820 fs/ocfs2/sysfile.c:102 Read of size 8 at addr ffff88800b767c00 by task kworker/u8:3/85 Call Trace:  ...  ocfs2_get_system_file_inode+0x780/0x820 fs/ocfs2/sysfile.c:102  ocfs2_wipe_inode+0x292/0xf70 fs/ocfs2/inode.c:840  ocfs2_delete_inode fs/ocfs2/inode.c:1155 [inline]  ocfs2_evict_inode+0x6c9/0x1170 fs/ocfs2/inode.c:1295  evict+0x38e/0x8f0 fs/inode.c:810  iput_final fs/inode.c:1914 [inline]  iput fs/inode.c:1966 [inline]  iput+0x55b/0x8b0 fs/inode.c:1926  ocfs2_recover_orphans+0x610/0xe40 fs/ocfs2/journal.c:2374  ocfs2_complete_recovery+0x5af/0xd00 fs/ocfs2/journal.c:1373  ...  [CAUSE] ocfs2_del_inode_from_orphan() uses i_dio_orphaned_slot to index the slot-local system inode cache. The dinode validator does not check this active slot, so an out-of-range value produces an invalid cache entry pointer that is dereferenced as an inode pointer.  [FIX] Reject an active i_dio_orphaned_slot outside the slot range during dinode validation, before DIO orphan recovery can consume it.",
