CVE-2022-49269 Details
Description
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. Sanitize the SFF/EFF CAN ID values before performing the address checks.
A vulnerability in the Linux kernel's ISOTP (Inter-Segment Transport Protocol) component has been addressed. The issue arose because the isotp_bind() function did not properly sanitize CAN ID values before performing address checks. This flaw allowed for the creation of a state machine status that could not be reached with a compliant CAN ID configuration. The vulnerability was triggered using specific CAN ID values that, when processed, effectively reduced to an 11-bit CAN ID of 0x001 for both sending and receiving.
