In the Linux kernel, the following vulnerability has been resolved:
HID: i2c-hid: fix potential buffer overflow in i2c_hid_get_report()
`i2c_hid_xfer` is used to read `recv_len + sizeof(__le16)` bytes of data
into `ihid->rawbuf`.
The former can come from the userspace in the hidraw driver and is only
bounded by HID_MAX_BUFFER_SIZE(16384) by default (unless we also set
`max_buffer_size` field of `struct hid_ll_driver` which we do not).
The latter has size determined at runtime by the maximum size of
different report types you could receive on any particular device and
can be a much smaller value.
Fix this by truncating `recv_len` to `ihid->bufsize - sizeof(__le16)`.
The impact is low since access to hidraw devices requires root.
