Just leaving this here for reference since it'll help with the ARM implementation for this: androidoffsec/art-kernel-toolkit#5 |
Fwiw bata24/GEF has sth implemented for this and I used it in the past, but I believe it can be improved. This may also be helpful: https://gist.github.com/disconnect3d/4fa1972f5b3148bf17995406490c0e70, at least to play with MSRs (skip the exploit part, take the read/write functions or/and constants). |

TL;DR: I want us to have a
msr
command for reading/writing to model specific registers.This should work by assembling and executing rdmsr/wrmsr instrucitons in the kernel and should only work/make sense in a qemu kernel context, since userspace can't rdmsr/wdmsr.
