        Exploit strategy:

        1) We have a leak with sys_thr_get_ucontext. We'll use this to leak a pointer
           to a cdev_priv object which we will leak by opening the dipsw device driver
        2) We can create a named object with sys_namedobj_create()
        3) We can set the lower 32-bits of offset 0's address in the object's structure
           via sys_mdbg_service. Set lower 32-bits to that of cdev's lower 32-bits
        4) We can now free() cdev with a call to sys_namedobj_delete()
        5) Now that the cdev object is free'd and we still maintain a reference, spray
           the heap to corrupt the object's backing memory
        6) Use a system call (ioctl) to trigger corrupted function pointer to get code execution
        7) Start a ROP chain in ring0 to write shellcode into kernel
        8) Jump to shellcode and return to usermode
        9) Apply patches for fun and profit!
