A faulty\nor malicious device can use that to make the kernel read and write\npast the 96-byte buffer in three ways:\n\n- scsi_sense_desc_find() is passed sb[7] + 8 as the buffer length, so\n  its clamp against sb[7] does nothing and the walk runs off the end.\n- A type-9 descriptor found near the end is filled in unchecked.\n- A new descriptor at sb[8 + len] needs len + 22 bytes, not len + 14,\n  so len 75..82 writes up to 8 bytes past the end.\n\nReproduced with KASAN under qemu, with the emulated ATAPI REQUEST SENSE\nreply patched:\n\n  BUG: KASAN: slab-out-of-bounds in scsi_sense_desc_find+0x1a5/0x210\n  BUG: KASAN: slab-out-of-bounds in ata_scsi_qc_complete+0x1a15/0x1a50\n\nBoth are gone with this patch, and a valid descriptor is still filled\nin."
