In the Linux kernel, the following vulnerability has been resolved:
net/dpaa2: Avoid explicit cpumask var allocation on stack
For CONFIG_CPUMASK_OFFSTACK=y kernel, explicit allocation of cpumask variable on stack is not recommended since it can cause potential stack overflow.
Instead, kernel code should always use *cpumask_var API(s) to allocate cpumask var in config-neutral way, leaving allocation strategy to CONFIG_CPUMASK_OFFSTACK.
Use *cpumask_var API(s) to address it.
