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.
