CONFIG_CPUMASK_OFFSTACK=y kernel, explicit allocation of cpumask\nvariable on stack is not recommended since it can cause potential stack\noverflow.\n\nInstead, kernel code should always use *cpumask_var API(s) to allocate\ncpumask var in config-neutral way, leaving allocation strategy to\nCONFIG_CPUMASK_OFFSTACK.\n\nUse *cpumask_var API(s) to address it.","state":0,"publishedAt":"2024-07-29T17:39:29.47+00:00","modifiedAt":"2026-10-15T00:47:42.434+00:00","affected":[{"ecosystem":"Vendor
