Subject: [PATCH 0/2] KVM: SVM: Fix a (very) unlikely UAF for GA Log IRQs
Date: Thu, 25 Jun 2026 15:09:31 -0700 [thread overview]
Message-ID: <20260625220933.3357733-1-seanjc@google.com> (raw)
Fix a potential UAF due to freeing vCPUs while they're still reachable through
the global hashed list used to handle GA Log notifications.
Sean Christopherson (2):
KVM: SVM: Remove VM from the GA Log notifier list before VM
destruction
KVM: SVM: Drop unnecessary avic_vm_destroy() call on init failure
