Trigon-Legacy is a Kernel exploit which exploits an integer overflow in the VM layer when creating memory entries. This allows arbitrary physical memory read/write, which is then used to build a tfp0 primitive. The techniques used are entirely deterministic and unusable in higher iOS versions, not overlapping with the original Trigon.
