Severity

8.8 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: HID: multitouch: fix out-of-bounds bit access on mt_io_flags mt_io_flags is a single unsigned long, but mt_process_slot(), mt_release_pending_palms() and mt_release_contacts() use it as a per-slot bitmap indexed by the slot number. That slot number is only bounded by td->maxcontacts, which is taken from the device's ContactCountMaximum feature report and can be up to 255, not by BITS_PER_LONG. As a result, a multitouch device that advertises a large contact count makes set_bit()/clear_bit() operate past the mt_io_flags word and corrupt the adjacent members of struct mt_device. The sticky-fingers release timer is the easiest way to reach this. mt_release_contacts() runs for (i = 0; i < mt->num_slots; i++) clear_bit(i, &td->mt_io_flags); with num_slots == maxcontacts. For maxcontacts around 250 the loop clears the bits that overlap td->applications.next, zeroing that list head, and the list_for_each_entry() that immediately follows then dereferences NULL. The kernel panics from timer (softirq) context. On a KASAN build this shows up as a general protection fault in mt_release_contacts() with a null-ptr-deref at offset 0x58, which is offsetof(struct mt_application, num_received). The state is reachable from an untrusted USB or Bluetooth HID multitouch device; no local privileges are required. Store the per-slot active state in a separately allocated bitmap sized for maxcontacts, the same pattern already used for pending_palm_slots, and keep only MT_IO_FLAGS_RUNNING in mt_io_flags. The two "mt_io_flags & MT_IO_SLOTS_MASK" arming checks become bitmap_empty(td->active_slots, td->maxcontacts). Move MT_IO_FLAGS_RUNNING back to bit 0. It was bumped to bit 32 by the same commit to leave the low byte for the slot bits; with the slot bits gone it fits in bit 0 again, which also keeps it within the unsigned long on 32-bit.

That slot number is only\nbounded by td-\u003emaxcontacts, which is taken from the device\u0027s\nContactCountMaximum feature report and can be up to 255, not by\nBITS_PER_LONG.\n\nAs a result, a multitouch device that advertises a large contact count\nmakes set_bit()/clear_bit() operate past the mt_io_flags word and\ncorrupt the adjacent members of struct mt_device. The sticky-fingers\nrelease timer is the easiest way to reach this. mt_release_contacts()\nruns\n\n\tfor (i = 0; i \u003c mt-\u003enum_slots; i++)\n\t\tclear_bit(i, \u0026td-\u003emt_io_flags);\n\nwith num_slots == maxcontacts. For maxcontacts around 250 the loop\nclears the bits that overlap td-\u003eapplications.next, zeroing that list\nhead, and the list_for_each_entry() that immediately follows then\ndereferences NULL. The kernel panics from timer (softirq) context. On a\nKASAN build this shows up as a general protection fault in\nmt_release_contacts() with a null-ptr-deref at offset 0x58, which is\noffsetof(struct mt_application, num_received).\n\nThe state is reachable from an untrusted USB or Bluetooth HID\nmultitouch device; no local privileges are required.\n\nStore the per-slot active state in a separately allocated bitmap sized\nfor maxcontacts, the same pattern already used for pending_palm_slots,\nand keep only MT_IO_FLAGS_RUNNING in mt_io_flags. The two\n\"mt_io_flags \u0026 MT_IO_SLOTS_MASK\" arming checks become\nbitmap_empty(td-\u003eactive_slots, td-\u003emaxcontacts).\n\nMove MT_IO_FLAGS_RUNNING back to bit 0. It was bumped to bit 32 by the\nsame commit to leave the low byte for the slot bits; with the slot bits\ngone it fits in bit 0 again, which also keeps it within the unsigned\nlong on 32-bit."

That slot number is only\nbounded by td-\u003emaxcontacts, which is taken from the device\u0027s\nContactCountMaximum feature report and can be up to 255, not by\nBITS_PER_LONG.\n\nAs a result, a multitouch device that advertises a large contact count\nmakes set_bit()/clear_bit() operate past the mt_io_flags word and\ncorrupt the adjacent members of struct mt_device. The sticky-fingers\nrelease timer is the easiest way to reach this. mt_release_contacts()\nruns\n\n\tfor (i = 0; i \u003c mt-\u003enum_slots; i++)\n\t\tclear_bit(i, \u0026td-\u003emt_io_flags);\n\nwith num_slots == maxcontacts. For maxcontacts around 250 the loop\nclears the bits that overlap td-\u003eapplications.next, zeroing that list\nhead, and the list_for_each_entry() that immediately follows then\ndereferences NULL. The kernel panics from timer (softirq) context. On a\nKASAN build this shows up as a general protection fault in\nmt_release_contacts() with a null-ptr-deref at offset 0x58, which is\noffsetof(struct mt_application, num_received).\n\nThe state is reachable from an untrusted USB or Bluetooth HID\nmultitouch device; no local privileges are required.\n\nStore the per-slot active state in a separately allocated bitmap sized\nfor maxcontacts, the same pattern already used for pending_palm_slots,\nand keep only MT_IO_FLAGS_RUNNING in mt_io_flags. The two\n\"mt_io_flags \u0026 MT_IO_SLOTS_MASK\" arming checks become\nbitmap_empty(td-\u003eactive_slots, td-\u003emaxcontacts).\n\nMove MT_IO_FLAGS_RUNNING back to bit 0. It was bumped to bit 32 by the\nsame commit to leave the low byte for the slot bits; with the slot bits\ngone it fits in bit 0 again, which also keeps it within the unsigned\nlong on 32-bit."
