kernel: mm: use-after-free in do_get_mempolicy function allows local DoS or other unspecified impact

The dogetmempolicy function in mm/mempolicy.c in the Linux kernel allows local users to hit a use-after-free bug via crafted system calls and thus cause a denial of service DoS or possibly have unspecified other impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out...
