The CAN frame modification rules allow bitwise logical operations that can be also applied to the can_dlc field. The privileged user &#34;root&#34; with CAP_NET_ADMIN can create a CAN frame modification rule that makes the data length code a higher value than the available CAN frame data size. In combination with a configured checksum calculation where the result is stored relatively to the end of the data (e.g. cgw_csum_xor_rel) the tail of the skb (e.g. frag_list pointer in skb_shared_info) can be rewritten which finally can cause a system crash. Because of a missing check, the CAN drivers may write arbitrary content beyond the data registers in the CAN controller&#39;s I/O memory when processing can-gw manipulated outgoing frames.</p> <p>An issue was discovered in can_can_gw_rcv in net/can/gw.c in the Linux kernel through 4.19.13.
