| [[HID_services|hidbus]] GetJoyPollingReceivedData buffer overflow
| hidbus GetJoyPollingReceivedData doesn't validate the u8 size used for memcpy, when copying the data to the output JoyPollingReceivedData. With 11.x, the size is now clamped to a maximum of 0x2C (regardless of polling-mode). Note that 0x2C is the data-size for JoyButtonOnlyPollingDataAccessor, the other polling-modes have a smaller size.
The hid-sysmodule code which writes data here does handle it properly: size is clamped to a max size, and the data-read uses a fixed-size anyway (hence there's no way to trigger this sdknso vuln with the hid-sysmodule tmem writing code).
This could only be exploited if one directly writes to the tmem when one has previously compromised hid-sysmodule, without using the normal tmem-writing func for this.
There are only a few [[HID_services#ExternalDevices|apps]] which use hidbus.
