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.
