In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Take the SRCU lock for page table walks in fault injection and AT emulation
walk s1() and kvm walk nested s2() expect to be called while holding
kvm->srcu to guard against memslot changes. While this is generally
the case, kvm at s12() and kvm find s1 desc level() call into the
respective walkers without taking kvm->srcu.
Fix by acquiring kvm->srcu prior to the table walk in both instances.
