Project:Branches: kymm/rtems:fix-can-queue-priority to rtems/rtos/rtems:main Author: mingming cheng ## Summary cpukit/dev/can: Reject out-of-range CAN queue priority can_bus_ioctl_create_queue() validates the priority supplied by user space via the RTEMS_CAN_CREATE_QUEUE ioctl. The valid range is 0 to RTEMS_CAN_QUEUE_PRIO_NR - 1, since RTEMS_CAN_QUEUE_PRIO_NR is the number of available priority classes. The previous check rejected only values greater than RTEMS_CAN_QUEUE_PRIO_NR, so a priority equal to RTEMS_CAN_QUEUE_PRIO_NR passed validation and was stored in edge_prio. Reject this value at the ioctl boundary instead of accepting an out-of-range priority and relying on later internal handling. Use >= so that only priorities within the documented range are accepted. ## Generative AI <!-- If you have used AI please use the "AI Contribution" template otherwise leave this blank see our fulls statement at https://www.rtems.org/generative-ai/--> <!-- Default settings, if it is a dropdown it will set after submission --> -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1310 You're receiving this email because of your account on gitlab.rtems.org.
