      "title": "HID: multitouch: stop the release timer from being rearmed on remove",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: multitouch: stop the release timer from being rearmed on remove\n\nmt_remove() quiesces the sticky-finger timer before stopping the\nhardware:\n\n    timer_delete_sync(&td->release_timer);\n\n    sysfs_remove_group(&hdev->dev.kobj, &mt_attribute_group);\n    hid_hw_stop(hdev);\n\ntimer_delete_sync() waits for a running callback and dequeues the timer,\nbut it does not stop the timer from being armed again. The transport is\nstill delivering reports at that point, and the report path rearms it:\n\n    if (app->quirks & MT_QUIRK_STICKY_FINGERS) {\n        if (td->mt_io_flags & MT_IO_SLOTS_MASK)\n            mod_timer(&td->release_timer,\n                      jiffies + msecs_to_jiffies(100));\n\nA report that arrives after timer_delete_sync() has returned therefore\nleaves the timer queued. td is allocated with devm_kzalloc() against\nhdev->dev, so it is freed when the driver is unbound, after mt_remove()\nreturns. When the timer fires afterwards, mt_expired_timeout()\ndereferences the freed td:\n\n    struct mt_device *td = timer_container_of(td, t, release_timer);\n    struct hid_device *hdev = td->hdev;\n\n    if (test_and_set_bit_lock(MT_IO_FLAGS_RUNNING, &td->mt_io_flags))\n\nSimply moving the teardown after hid_hw_stop() does not fix this on its\nown, because mt_expired_timeout() calls mt_release_contacts(), which\nwalks hdev->inputs; the timer still has to be quiesced before\nhid_hw_stop() tears the input devices down.\n\nUse timer_shutdown_sync() instead, which additionally makes any later\nmod_timer() a no-op, so neither ordering constraint has to be traded off\nagainst the other. This is the final-teardown pattern the function was\nintroduced for, and hid-wiimote already uses it for the same reason.",
