- Summary
- KVM: arm64: Fix the descriptor address in __kvm_at_swap_desc()
- Details
-
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 + offset8. ;-)
Fix it.
