CVSROOT: /cvs Module name: src Changes by: [email protected] 2020/02/15 15:59:55Modified files: sys/arch/amd64/amd64: vmm.c Log message: Add bounds check on addresses passed from guests in pvclock. Fixes an issue where a guest can write to host memory by passing bogus addresses.
I'm a bit confused here. It is not because the GPAs are contiguous that the HPAs are too. If the structure crosses a page, the guest still can write to host memory.
