WebbSo let's get rid of our dependency on the large model for KASLR, by: - reducing the full randomization range to 4 GB, thereby ensuring that ADRP references between modules and the kernel are always in range, - reduce the spillover range to 4 GB as well, so that we fallback to a region that is still guaranteed to be in range - move the randomization …
