DPC Stack Collection is yet another area to mine for Execution Residue and Rough Stack Traces. Some DPC Stacks may be visible in Stack Trace Collections such as from CPUs.

Each CPU has a DPC stack for execution of queued DPCs. We can get its base stack region address from the corresponding _KPRCB structure for each CPU. The stack region limit can be calculated from the KeKernelStackSize Module Variable:
