In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: nv: Write ESR_EL2 for injected nested SError exceptions
kvm_inject_el2_exception() writes ESR_EL2 for synchronous exceptions
but not for SError. enter_exception64() does not write ESR_ELx for any
exception type, so the constructed syndrome is dropped. A guest L2
hypervisor taking a nested SError observes stale ESR_EL2.
This affects both kvm_inject_nested_serror() and the EASE path in
kvm_inject_nested_sea().
Write ESR_EL2 for except_type_serror, matching except_type_sync.
