Analyze and fix the following issue in the Linux kernel code: cpumask: fix bug in use cpumask_var_t in irq_desc
Problem Details: Impact: fix bug where new irq_desc uses old cpumask pointers which are freed. As Yinghai pointed out, init_copy_one_irq_desc() copies the old desc to the new desc overwriting the cpumask pointers. Since the old_desc and the cpumask pointers are freed, then memory corruption will occur if these old po...
