Description
A flaw was found in the Linux kernel's comedi driver. An exceptional exit case in the do_cmd_ioctl() function, where a runflags variable is not properly set, prevents the chanlist memory from being freed. This memory leak can lead to a denial of service (DoS) condition, potentially impacting system stability and availability.
