kernel: heap/stack gap jumping via unbounded stack allocations

A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap or different memory region and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack guard gap, cause controlled memory corruption on process sta...
