kernel: net/iucv: Avoid explicit cpumask var allocation on stack

A flaw was found in the Linux kernel's net/iucv component. This vulnerability arises when a specific kernel configuration CONFIGCPUMASKOFFSTACK=y is enabled, allowing for explicit allocation of cpumask variables directly on the system's memory stack. An attacker could exploit this to trigger a...
