Subject: [PATCH v2 0/2] KVM: nVMX: eVMCS consistency check fixes
Date: Thu, 5 Nov 2026 11:07:31 -0800 [thread overview]
Message-ID: <20261105190733.3741959-1-seanjc@google.com> (raw)
Fix two benign-for-real-guests bugs where KVM incorrectly performs eVMCS
consistency checks on VMCS fields that are supposed to be ignored.
v2: Properly guard the checks instead of simply deleting the WARN.
v1: https://lore.kernel.org/all/f1f39118-2e1b-476b-9a84-ef7d56412bdc@tum.de
Sean Christopherson (2):
KVM: nVMX: Do eVMCS consistency check on secondary controls iff
they're enable
KVM: nVMX: Do eVMCS consistency check on VMFUNC controls iff they're
enable
