In the Linux kernel, the following vulnerability has been resolved: can: ems_usb: validate CPC message lengths ems_usb_read_bulk_callback() walks CPC messages packed in one USB receive buffer. Check that each declared message fits in the URB payload. Also require the type-specific payload to cover the fields used by the CAN, state, error and overrun handlers. A flaw was found in the Linux kernel's `ems_usb` module. This vulnerability occurs because the `ems_usb_read_bulk_callback()` function, which processes Controller Area Network (CAN) Protocol Converter (CPC) messages from a USB receive buffer, does not properly validate the lengths of these messages. An attacker could exploit this by sending specially crafted CPC messages, potentially leading to a denial of service due to a format error when processing the malformed data.
