Subject: [PATCH v2 0/2] KVM: arm64: Sanitise host vCPU fields copied in flush_hyp_vcpu()

From: Hyunwoo Kim <[email-masked]>
Date: Fri, 5 Jun 2026 00:12:01 +0900

flush_hyp_vcpu() copies the host vCPU context and vGIC state into the
hyp's private vCPU on every run. This series sanitises two fields that
it currently copies verbatim (host -> EL2): __hyp_running_vcpu is
cleared in the guest context, and used_lrs is bounded by the number of
implemented list registers.

v1 -> v2: split into two patches, one per field, per review.

Hyunwoo Kim (2):
  KVM: arm64: Clear __hyp_running_vcpu when flushing the pKVM hyp vCPU
  KVM: arm64: Bound used_lrs when flushing the pKVM hyp vCPU
