CVE-2026-89727

CVE-2026-89727 affects the Linux kernel KVM arm64 GICv2 implementation. In vgic_v2_deactivate(), a guest-written INTID is passed directly to vgic_get_vcpu_irq(), where a failed lookup triggers WARN_ON_ONCE()—treated as a "can't happen" condition. Since GICv2 has no LPIs, any INTID outside the SGI...
