Risk 72
Severity

AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

In the Linux kernel, the following vulnerability has been resolved:

KVM: arm64: Fix the descriptor address in kvmatswapdesc()

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.
