Input: uinput - zero-initialize uinput_ff_upload_compat to avoid info leak

2025-10-15T10:00:24+00:00

commit d3366a04770eea807f2826cbdb96934dd8c9bf79 upstream. Struct ff_effect_compat is embedded twice inside uinput_ff_upload_compat, contains internal padding. In particular, there is a hole after struct ff_replay to satisfy alignment requirements for the following union member. Without clearing the structure, copy_to_user() may leak stack data to userspace. Initialize ff_up_compat to zero before filling valid fields.

Input: atmel_mxt_ts - allow reset GPIO to sleep

2025-10-15T10:00:23+00:00

commit c7866ee0a9ddd9789faadf58cdac6abd7aabf045 upstream. The reset GPIO is not toggled in any critical section where it couldn't sleep, allow the reset GPIO to sleep. This allows the driver to operate reset GPIOs connected to I2C GPIO expanders.

Input: i8042 - add TUXEDO InfinityBook Pro Gen10 AMD to i8042 quirk table

commit 1939a9fcb80353dd8b111aa1e79c691afbde08b4 upstream. Occasionally wakes up from suspend with missing input on the internal keyboard. Setting the quirks appears to fix the issue for this device as well.

Input: iqs7222 - avoid enabling unused interrupts

2025-09-19T14:35:48+00:00

commit c9ddc41cdd522f2db5d492eda3df8994d928be34 upstream. If a proximity event node is defined so as to specify the wake-up properties of the touch surface, the proximity event interrupt is enabled unconditionally. This may result in unwanted interrupts. Solve this problem by enabling the interrupt only if the event is mapped to a key or switch code.

Input: gpio-keys - fix a sleep while atomic with PREEMPT_RT

2025-08-01T08:48:39+00:00

commit f4a8f561d08e39f7833d4a278ebfb12a41eef15f upstream. When enabling PREEMPT_RT, the gpio_keys_irq_timer() callback runs in hard irq context, but the input_event() takes a spin_lock, which isn't allowed there as it is converted to a rt_spin_lock().

Input: iqs7222 - explicitly define number of external channels

2025-07-10T14:05:10+00:00

commit 63f4970a1219b5256e8ea952096c86dab666d312 upstream. The number of external channels is assumed to be a multiple of 10, but this is not the case for IQS7222D. As a result, some CRx pins are wrongly prevented from being assigned to some channels. Address this problem by explicitly defining the number of external channels for cases in which the number of external channels is not equal to the total number of available channels.

commit 4cf65845fdd09d711fc7546d60c9abe010956922 upstream. The cs40l50_upload_owt() function allocates memory via kmalloc() without checking for allocation failure, which could lead to a NULL pointer dereference. Return -ENOMEM in case allocation fails.
