In the Linux kernel, the following vulnerability has been resolved: can: ems_usb: ems_usb_read_bulk_callback(): check the proper length of a message When looking at the data in a USB urb, the actual_length is the size of the buffer passed to the driver, not the transfer_buffer_length which is set by the driver as the max size of the buffer. When parsing the messages in ems_usb_read_bulk_callback() properly check the size both at the beginning of parsing the message to make sure it is big enough for the expected structure, and at the end of the message to make sure we don't overflow past the end of the buffer for the next message. A flaw was found in the Linux kernel's ems_usb module. This vulnerability occurs because the system does not properly verify the length of messages it receives. An attacker could exploit this weakness by sending specially crafted messages, potentially causing the system to crash (Denial of Service) or, in some cases, execute unauthorized code.
