      "title": "ata: libata-scsi: bound the ATA passthru sense descriptor writes",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nata: libata-scsi: bound the ATA passthru sense descriptor writes\n\nWhen an ATA PASS-THROUGH command to an ATAPI device fails, the sense\nbuffer holds the device's REQUEST SENSE reply, and\nata_scsi_set_passthru_sense_fields() trusts its additional length\nbyte, sb[7], when adding the ATA Status Return descriptor.  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.",
