CVE-2026-46295 kernel: KVM: x86: Do IRR scan in __kvm_apic_update_irr even if PIR is empty
bugzilla·2026-06-08
CVE-2026-46295 [MEDIUM] CVE-2026-46295 kernel: KVM: x86: Do IRR scan in __kvm_apic_update_irr even if PIR is empty
CVE-2026-46295 kernel: KVM: x86: Do IRR scan in __kvm_apic_update_irr even if PIR is empty
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Do IRR scan in __kvm_apic_update_irr even if PIR is empty
Fall back to apic_find_highest_vector() when PID.ON is set but PIR
turns out to be empty, to correctly report the highest pending interrupt
from the existing IRR.
In a nested VM stress test, the following WARNING fires in
vmx_check_nested_events() when kvm_cpu_has_interrupt() reports a pending
interrupt but the subsequent kvm_apic_has_interrupt() (which invokes
vmx_sync_pir_to_irr() again) returns -1:
WARNING: CPU: 99 PID: 57767 at arch/x86/kvm/vmx/nested.c:4449 vmx_check_nested_events+0x6bf/0x6e0 [kvm_intel]
