Description
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Transfer the hyp stack pages out of the host stage-2
fix_host_ownership() walks only the linear-map alias of each memblock
region, and the per-CPU hyp stack, mapped in the private VA range for
its guard page, has none.
Walk each stack's VA range with the same walker.
