If a zero length is passed to kmalloc() it returns 0x10, which is not a valid address. gss_verify_mic() subsequently crashes when it attempts to dereference that pointer. Instead of allocating this memory on every call based on an untrusted size value, use a piece of dynamically-allocated scratch memory that is always available.
