  "description": "In the Linux kernel, the following vulnerability has been resolved:  Input: iforce - bound the device-reported force-feedback effect index  iforce_process_packet() handles a status report (packet id 0x02) by taking a force-feedback effect index straight from the device wire and using it to address the per-effect state array:  \ti = data[1] \u0026 0x7f; \tif (data[1] \u0026 0x80) { \t\tif (!test_and_set_bit(FF_CORE_IS_PLAYED, \t\t\t\t      iforce-\u003Ecore_effects[i].flags)) \t\t\t... \t} else if (test_and_clear_bit(FF_CORE_IS_PLAYED, \t\t\t\t      iforce-\u003Ecore_effects[i].flags)) { \t\t... \t}  The index is masked only with 0x7f, so it ranges 0..127, but core_effects[] holds only IFORCE_EFFECTS_MAX (32) entries.  For an index of 32..127 the test_and_set_bit()/test_and_clear_bit() is an out-of-bounds single-bit read-modify-write past the array.  core_effects[] is the second-to-last member of struct iforce, so the write lands in the trailing members and beyond the embedding kzalloc()\u0027d iforce_serio / iforce_usb object.  data[1] is unvalidated device payload on both transports (the USB interrupt endpoint and serio), and the status path is not gated on force feedback being present, so a malicious or counterfeit device can set or clear a bit at an attacker-chosen offset past the object.  Reject an out-of-range index instead of indexing with it.  Bound against the array dimension IFORCE_EFFECTS_MAX rather than dev-\u003Eff-\u003Emax_effects so the check guarantees memory safety regardless of how many effects the device registered.  A legitimate \u0022effect started/stopped\u0022 status always carries an index below IFORCE_EFFECTS_MAX, so well-formed devices are unaffected; the neighbouring mark_core_as_ready() loop is already bounded and is left untouched.",
