Description

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.
