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

can: isotp: sanitize CAN ID checks in isotp_bind()

Syzbot created an environment that lead to a state machine status that can not be reached with a compliant CAN ID address configuration. The provided address information consisted of CAN ID 0x6000001 and 0xC28001 which both boil down to 11 bit CAN IDs 0x001 in sending and receiving.
