JEP137 documents ID Code assignments for: 1) the Algorithm-specific Command Set and Control Interfaces and 2) the Device Interfaces. It is published as needed when additions are made to either of these lists of codes. Additions to Table 1 The Algorithm Command Set and Control Interface ID ...
Besides, it's also eminently the case that, having done amem::transmuteon the function pointer itself, that the author of that codediddemonstrate intent. That is, it is not clear to me that this was not, in fact, a "proper cast". ...
Cross-DSO CFI requires ASLR and PaX NOEXEC at a minimum to be effective. If an attacker knows the address of the metadata pages, the attacker can first perform data-only attacks for later code execution/code reuse attacks. Similarily, if an attacker is able to mark non...
Game design: a case Utilizing the proposed VR rehabilitation serious game design framework CFI, this paper develops an upper limb HMD-VR rehabilitation serious game tailored for patients with mild to moderate stroke as an example. The game is developed via the Unity3D game engine. The utilization...
For a CFI with address range of 0x05000000 to 0x05FFFFFF, shouldnt the code I posted work for writing 0x20000 values to the last block? Shouldnt the code example given in the software dev handbook (p 6-22) work?! Do I need finegrained access? As for the NEEK/An429 example... ...
The usefulness of equating a register to a fixed label is probably limited to the return address register. Here, it can be useful to mark a code segment that has only one return address which is reached by a direct branch and no copy of the return address exists in memory or another reg...
Figure 4. An example of a kernel panic caused by a CFI failure. Another potential pitfall are address space conflicts, but this should be less common in driver code. LLVM's CFI checks only understand kernel virtual addresses and any code that runs at another exception level or makes an indi...
