In the Linux kernel, the following vulnerability has been resolved:

can: peak_usb: validate uCAN receive record lengths

pcan_usb_fd_decode_buf() walks uCAN records packed in one USB
receive buffer.

Require each record to contain the fixed header for its type, and verify
CAN payload bytes before copying them into the skb.
