[NTOSKRNL]: Add a helper function such that user-mode cannot pass certain kernel-only object attributes to ObOpenObjectByPointer. [NTOSKRNL]: Make \Device\PhysicalMemory OBJ_KERNEL_EXCLUSIVE [NTOSKRNL]: Deny access to user-mode when opening a handle to an object with OBJ_KERNEL_EXCLUSIVE [NTOSKRNL]: Fix NtOpenProcess, NtOpenThread, NtOpenThreadTokenEx, NtOpenProcessTokenEx to use the helper function. Should fix Rtl using OBJ_KERNEL_HANDLE in user-mode. Thanks to ThFabba for finding out these bugs, and the hbelusca for adding a missing check to NtOpenProcessTokenEx. svn path=/trunk/; revision=69340 |
