Another CVE/exploit that might have worked regardless of MTE :) → github.com/asahilina/agx-… it hijacks Apple GPU firmware → GPU gains full RAM R/W. MTE only guards CPU loads/stores, GPU DMA is outside of its scope.
I’ve brought you a real iOS MTE bypass retrospectively: the overflow happens inside the co-processor (no MTE), then abuses trusted RPCs to gain kernel R/W — sidestepping MTE on the AP entirely. googleprojectzero.blogspot.com/2022/06/curiou…

We have received reports @HyperDbg's latest release shows unexpected behavior. As it turns out, this is due to a compiler optimization bug in Visual Studio 17.14.8 and 17.14.9. We have pushed a temporary workaround fixing the build. Thanks for reporting! (1/2)
