### CVE-2016-1758

CVE-2016-1758 is an information leak caused by copying out uninitialized bytes
of kernel stack to user space. By comparing leaked kernel pointers with fixed
reference addresses it is possible to recover the kernel slide.

### CVE-2016-1828

CVE-2016-1828 is a use-after-free during object deserialization. By passing a
crafted binary-serialized dictionary into the kernel, it is possible to trigger
a virtual method invocation on an object with a controlled vtable pointer.
