In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Fix the descriptor address in __kvm_at_swap_desc()
Using "(u64 __user *)hva + offset" to get the virtual addresses of S1/S2
descriptors looks really wrong, if offset is not zero. What we want to get
for swapping is hva + offset, not hva + offset*8. ;-)
Fix it.
