2025-10-17Input: pegasus-notetaker - fix potential out-of-bounds accessSeungjin Bae
In the pegasus_notetaker driver, the pegasus_probe() function allocates the URB transfer buffer using the wMaxPacketSize value from the endpoint descriptor. An attacker can use a malicious USB descriptor to force the allocation of a very small buffer. Subsequently, if the device sends an interrupt packet with a specific pattern (e.g., where the first byte is 0x80 or 0x42), the pegasus_parse_packet() function parses the packet without checking the allocated buffer size. This leads to an out-of-bounds memory access.

2025-10-13Input: goodix - remove setting of RST pin to inputMartyn Welch
The reset line is being set to input on non-ACPI devices apparently to save power. This isn't being done on ACPI devices as it's been found that some ACPI devices don't have a pull-up resistor fitted. This can also be the case for non-ACPI devices, resulting in: [ 941.672207] Goodix-TS 1-0014: Error reading 10 bytes from 0x814e: -110 [ 942.696168] Goodix-TS 1-0014: Error reading 10 bytes from 0x814e: -110 [ 945.832208] Goodix-TS 1-0014: Error reading 10 bytes from 0x814e: -110 This behaviour appears to have been initialing introduced in ec6e1b4082d9. This doesn't seem to be based on information in either the GT911 or GT9271 datasheets cited as sources of information for this change. Thus it seems likely that it is based on functionality in the Android driver which it also lists. This behaviour may be viable in very specific instances where the hardware is well known, but seems unwise in the upstream kernel where such hardware requirements can't be guaranteed. Remove this over optimisation to improve reliability on non-ACPI devices.

2025-10-01Drivers: hv: Add CONFIG_HYPERV_VMBUS optionMukesh Rathor
At present VMBus driver is hinged off of CONFIG_HYPERV which entails lot of builtin code and encompasses too much. It's not always clear what depends on builtin hv code and what depends on VMBus. Setting CONFIG_HYPERV as a module and fudging the Makefile to switch to builtin adds even more confusion. VMBus is an independent module and should have its own config option. Also, there are scenarios like baremetal dom0/root where support is built in with CONFIG_HYPERV but without VMBus. Lastly, there are more features coming down that use CONFIG_HYPERV and add more dependencies on it. So, create a fine grained HYPERV_VMBUS option and update Kconfigs for dependency on VMBus.

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.

2025-09-24Input: pm8941-pwrkey - disable wakeup for resin by defaultLuca Weiss
'Resin' (*Res*et *In*put) is usually connected to a volume down button on devices, which is usually not expected to wake up the device from suspend. On the other hand, pwrkey should keep wakeup on. So do not enable wakeup for resin unless the "wakeup-source" property is specified in devicetree. Note, that this does change behavior by turning off wakeup by default for 'resin' and requiring a new dt property to be added to turn it on again. But since this is not expected behavior in the first place, and most users will not expect this, I'd argue this change is acceptable.

Add a simple driver for the Himax HX852x(ES) touch panel controller, with support for multi-touch and capacitive touch keys. The driver is somewhat based on sample code from Himax.
