Description: Apply upstream fix for potential KVM irqfd vulnerability (CVE-2017-1000252) in kvm_irqfd cloned code. HSD#: TBD. Related Pull Request: N/A.
Impact Analysis:
What is the scope of the change?
Small and localized change (input validation / sanity checks) in virt/kvm/eventfd.c; low risk and business-as-usual security hardening aligned with upstream.
Purpose of the change?
To align cloned code with upstream security patch and prevent invalid guest-triggered inputs from causing unintended behavior (potential DoS). Objective is clear and directly matches upstream fix.
Reach of the change?
Primarily impacts the KVM irqfd path (virt/kvm/eventfd.c). No functional changes expected outside KVM; only affects callers exercising irqfd with invalid parameters.
Regression Test result: N/A (please attach regtest link if available).
