CVE-2026-64286

CVE-2026-64286 affects the Linux kernel’s KVM on arm64. The vulnerability arises in flush_hyp_vcpu(): it copies the host vCPU context into the hyp private vCPU on every run. The guest-context resolver (ctxt_to_vcpu()) expects a NULL __hyp_running_vcpu (only set on the host); since the host’s valu...
