The vulnerability exists in kldstat(2) system call implementation  due to kernel does not properly clear the memory of the kld_file_stat structure before filling the data.  Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information from the kernel stack is possible.
