Input: iforce - validate input packet lengths

2026-08-23T12:26:56+00:00

commit 5751c781d3c97ab6ce0e2a966156ed882152c415 upstream. iforce_process_packet() reads fixed fields from joystick, wheel and status packets without first checking their lengths. In particular, the shared hats-and-buttons helper unconditionally reads data[6]. The status tail is a sequence of 16-bit effect addresses, but an incomplete final address is also consumed. A successful zero-length USB URB additionally reads the packet ID before the common parser is called. Reject the zero-length USB transfer, require the seven-byte joystick and wheel prefixes and the two-byte status prefix, and consume only complete status-tail addresses.

Input: psxpad-spi - set driver data before use

2026-08-23T12:26:56+00:00

commit 732f38c36059e68ba3b4b89c56911d777fd3185c upstream. psxpad_spi_suspend() retrieves the controller state with spi_get_drvdata(), but probe never stores it, so suspend dereferences a NULL pointer. Store it during probe.

Input: maplecontrol - set driver data before registering input device

2026-07-18T14:53:35+00:00

commit fe938ee497d58c644f6910cfe6ae155f6fb3e523 upstream. Set maple driver data before calling input_register_device() to ensure that it is available if the device is opened immediately and the callback is triggered.

Input: iforce - bound the device-reported force-feedback effect index

2026-07-18T14:53:34+00:00

commit 0e9943d2e4c63496b6ca84bc66fd3c71d40558e2 upstream. 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: i = data[1] & 0x7f; if (data[1] & 0x80) { if (!test_and_set_bit(FF_CORE_IS_PLAYED, iforce->core_effects[i].flags)) ... } else if (test_and_clear_bit(FF_CORE_IS_PLAYED, iforce->core_effects[i].flags)) { ... } 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()'d 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->ff->max_effects so the check guarantees memory safety regardless of how many effects the device registered. A legitimate "effect started/stopped" 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.

Input: xpad - fix out-of-bounds access for Share button

2026-06-09T10:28:35+00:00

commit 6cdc46b38cf146ce81d4831b6472dbf7731849a2 upstream. xpadone_process_packet() receives len directly from urb->actual_length and uses it to index the share-button byte at data[len - 18] or data[len - 26]. Since both len and data[0] are under the device's control, a broken controller can send a GIP_CMD_INPUT packet with actual_length < 18 (e.g. 5 bytes) and reach this code path, causing accesses beyond the actual array. Fix this by calculating the offset and checking bounds against the packet length.

Input: xpad - add support for Razer Wolverine V3 Pro

commit e2b0ae529db4766584e77647cefe3ec15c3d842e upstream. Add device IDs for the Razer Wolverine V3 Pro controller in both wired (0x0a57) and wireless 2.4 GHz dongle (0x0a59) modes. The controller uses the Xbox 360 protocol (vendor-specific class, subclass 93, protocol 1) on interface 0 with an identical 20-byte input report layout, so no additional processing is needed.
