Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved, related to the isotp bind() function. The issue arose when Syzbot created an environment that led to a state machine status that cannot 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. The fix involves sanitizing the SFF/EFF CAN ID values before performing the address checks.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
