Problem Description:
The 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.
Impact:
Some bytes from the kernel stack can be observed in
userspace.
