  3. CVE-2022-49269
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: can: isotp: sanitize CAN ID checks in isotp_bind() Syzbot creó un entorno que condujo a un estado de máquina de estados al que no se puede acceder con una configuración de dirección CAN ID compatible. La información de dirección proporcionada consistía en CAN ID 0x6000001 y 0xC28001, que se reducen a 11 bits CAN ID 0x001 en envío y recepción. Sanitize los valores SFF/EFF CAN ID antes de realizar las comprobaciones de dirección.
